Nepal charges VAT (Value Added Tax) at a standard rate of 13%. Use 13 as your GST rate in this calculator for Nepal-specific calculations.

GST exclusive means the price does not include tax — tax is added on top. GST inclusive means the price already includes the tax amount. This calculator handles both scenarios.

Enter 5000 as the price and 13 as the GST rate, select "Add GST", and click Calculate. The tool will show you the GST amount (रु 650) and the total price inclusive of GST (रु 5,650).

Yes. Just enter the applicable Indian GST rate (5%, 12%, 18%, or 28%) in the rate field.

Yes. It checks for common grammar rules used in formal English writing including subject-verb agreement, tense consistency, article usage, and more.

Absolutely. Paste your email draft into the tool, check for errors, and copy the corrected version back into your email client.

The tool primarily checks standard English. For British vs American variations, note that some spelling differences (e.g., "colour" vs "color") may be flagged.

No. Your text is processed in the browser session only and is not stored on any server.

Yes, no payment or account required.

UUID stands for Universally Unique Identifier. It is a 128-bit label used in computing to identify information uniquely without requiring a central authority to assign IDs. A standard UUID looks like: 550e8400-e29b-41d4-a716-446655440000.

UUID v1 is generated based on the current timestamp and MAC address of the device. UUID v4 is fully randomly generated, which makes it more private and the most commonly used version.

Yes. UUID v4 identifiers are safe for use as primary keys in databases, API tokens, session IDs, and other unique identifier needs.

UUID v4 uses 122 bits of randomness. The probability of generating a duplicate is practically zero — around 1 in 5.3 × 10^36.

Base64 is an encoding scheme that converts binary data or text into a set of 64 ASCII characters (A–Z, a–z, 0–9, +, /). It's used to safely transmit data in environments that only support text, such as URLs, emails, and JSON.

No. Base64 is encoding, not encryption. It is not a security measure — anyone can decode a Base64 string. If you need to protect data, use actual encryption (AES, RSA, etc.).

The "==" padding characters are added to make the output length a multiple of 4, as required by the Base64 specification.

This tool currently handles text/string encoding. For image-to-Base64 conversion, you would need a file-based encoder.

A HEX color code is a 6-digit code (e.g., #FF5733) used in web design and CSS to represent colors. The code combines red, green, and blue values in hexadecimal format.

RGB (Red, Green, Blue) defines colors by mixing light values from 0 to 255 for each channel. HSL (Hue, Saturation, Lightness) defines colors by their hue angle, saturation percentage, and lightness percentage — often more intuitive for designers.

The tool works with color codes. For named CSS colors, find their HEX equivalent (e.g., "navy" = #000080) and enter it in the HEX field.

Yes. Pick a color and compare it to Tailwind's color palette. The HEX code can also be used in custom Tailwind config.

Yes. Generate as many citations as you need — there are no daily limits.

No. The rewriter is designed to preserve the original meaning while changing the wording, structure, and phrasing of the content.

Yes, but always review the output carefully. When paraphrasing for academic work, ensure the rewritten version accurately reflects the original source and always cite the source properly.

The rewriter produces unique phrasing, but it is always good practice to run the output through a plagiarism checker before publishing.

For best results, paste content in manageable chunks (up to 500–1000 words). Very long texts may produce better results when processed in sections.

Yes, completely free to use.

Enter 20 in the percentage field and 1500 in the number field under "Basic Percentage", then click Calculate. The answer is 300.

Use the "Percentage Change" tab, enter 80 as the original value and 100 as the new value. The result is a 25% increase.

The basic formula is: Percentage = (Part / Whole) × 100. For example, if you scored 45 out of 60, your percentage is (45/60) × 100 = 75%.

Yes. Use "Basic Percentage" to find X% of the original price. That result is the discount amount. Subtract it from the original price to get the discounted price.

The tool shows two character counts — one including spaces and one excluding spaces — so you always have the exact figure you need.

Reading time is calculated using an average reading speed of approximately 200 words per minute, which is a standard estimate for adult readers.

Most SEO experts recommend 1,000 to 2,500 words for competitive blog posts. For informational guides or pillar content, 2,000+ words generally performs better in Google search.

Keep your meta description between 130 and 160 characters (including spaces) to avoid Google truncating it in search results.

According to standard BMI classifications: Below 18.5 = Underweight, 18.5 to 24.9 = Normal/Healthy, 25.0 to 29.9 = Overweight, 30.0 and above = Obese.

BMI can be misleading for athletes and people with high muscle mass, since muscle weighs more than fat. A muscular person may have a high BMI but still be very healthy. For a more complete picture, consider body fat percentage or waist-to-height ratio.

BMI = Weight (kg) ÷ Height² (m²). For example: if you weigh 70 kg and are 1.75 m tall, BMI = 70 ÷ (1.75 × 1.75) = 22.9 (Normal range).

This calculator is designed for adults (18+). Children use age- and sex-specific BMI-for-age charts (called BMI percentiles), not the same standard adult ranges.

Your monthly payment is calculated based on the loan amount (home price minus down payment), the interest rate, and the loan term using the standard amortization formula.

No, this calculator estimates principal and interest only. Property taxes, home insurance, and HOA fees should be added separately for a full monthly cost estimate.

A larger down payment reduces your loan amount, which lowers both your monthly payment and the total interest paid over the loan term.

A 15-year mortgage has higher monthly payments but significantly less total interest paid, while a 30-year mortgage has lower monthly payments but more interest over time.

Yes, it's completely free with no sign-up required.

A strong password should be at least 16 characters long, combining uppercase, lowercase, numbers, and symbols for the best security.

Yes, passwords are generated using a randomization process that combines your selected character types to create an unpredictable, unique password.

No, passwords are generated instantly in your browser and are not stored, logged, or sent anywhere, keeping your data completely private.

The strength indicator (e.g., STRONG) gives you instant feedback on how secure your password is based on its length and character variety.

Enter the net amount and the VAT rate, then click Calculate. The tool will add the VAT and show you the total gross amount including tax.

Switch to the gross-to-net mode, enter the gross (total) amount and the VAT rate, and the tool will calculate the original net amount before tax.

VAT amount = Net Amount × (VAT Rate / 100). The gross amount is then Net Amount + VAT amount.

Yes, you can enter any VAT or tax rate percentage, making it suitable for VAT, GST, or sales tax calculations in any country.

Yes, it's completely free with no sign-up required.

Formatting adds proper indentation, line breaks, and spacing to your JSON, making it human-readable and easier to debug.

Format makes JSON readable with indentation for humans, while Minify removes all unnecessary whitespace to make the JSON smaller and faster to transmit over a network.

Yes, if your JSON has syntax errors like missing quotes, trailing commas, or mismatched brackets, the tool will help you identify the issue.

No, the formatting and minifying happens directly in your browser, so your data stays private and is never stored or uploaded.

Yes, completely free with no sign-up or installation required.

Yes. If your tool has a "no duplicates" option, enable it to ensure each generated number appears only once in the results.

Absolutely. Set your range (e.g., 1 to 49 for many lotteries), choose how many numbers you need, and the generator will pick random numbers within that range.

The numbers are generated using your browser's built-in random number function (Math.random()), which produces cryptographically unpredictable numbers suitable for most casual and research use cases.

The default generator produces integers (whole numbers). For decimal ranges, note that the generator focuses on whole numbers by default.

Yes, completely free with no limits.

°F = (°C × 9/5) + 32. For example, 100°C = 212°F (boiling point of water).

°C = (°F − 32) × 5/9. For example, 98.6°F = 37°C (normal human body temperature).

Absolute zero is 0 Kelvin, which equals −273.15°C or −459.67°F. It is the theoretical lowest possible temperature.

Celsius and Fahrenheit are equal at −40 degrees (−40°C = −40°F).

Yes, completely free to use with no registration needed.

This tool supports UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, and alternating case.

No. All conversion happens locally in your browser. Your text never leaves your device, making this a fully private tool.

Title Case capitalizes the first letter of every major word (e.g., "The Quick Brown Fox"). Sentence case only capitalizes the first letter of the first word in each sentence (e.g., "The quick brown fox").

Yes! This is perfect for developers. Paste your variable names or text and convert to camelCase or snake_case instantly.

There is no set limit for typical use. Very large texts may vary in performance based on your browser.

Yes, by default the counter includes spaces in the total character count. Many platforms like Twitter count spaces as characters.

Twitter/X allows up to 280 characters per tweet, including spaces and punctuation.

Google typically displays 150–160 characters in search results. Keep your meta descriptions within this range for best results.

Yes. The counter works with Unicode text including Nepali Devanagari characters.

D6 refers to a 6-sided die — the standard die most people are familiar with. The number after "D" always refers to the number of sides on that die (D4 = 4 sides, D20 = 20 sides, etc.).

Yes! D&D uses D4, D6, D8, D10, D12, and D20 dice — all supported by this tool. Roll ability checks, attacks, damage, and skill checks easily.

Yes. Select the number of dice and all results are shown individually along with the combined total.

Yes. Each roll uses your browser's random number function to simulate an unbiased dice roll.

Yes, completely free — no sign-up needed.

Yes. The result is generated using a random number function that gives exactly 50% probability to both heads and tails, simulating a perfectly fair coin.

Of course! That's one of the most popular uses. Assign an outcome to Heads and an outcome to Tails, then flip and let chance decide.

No. The 50/50 probability is constant regardless of what device or browser you use.

Unlimited. Flip as many times as you like — there are no restrictions.

Yes, completely free with no account needed.

Schema markup is structured data code (usually JSON-LD) added to a webpage that helps search engines understand the content on that page. It is based on vocabulary from Schema.org.

Schema markup itself is not a direct ranking factor, but it can enable rich results in Google search (like FAQ dropdowns and article snippets), which typically increases click-through rates and visibility.

JSON-LD (JavaScript Object Notation for Linked Data) is the recommended format by Google for adding schema markup. It is placed in a
