Unit Converter
Unit Converter converts values across eight measurement categories using client-side processing in your browser, ensuring no data uploads and full privacy.
Unit Converter is a browser-based tool that converts units in eight categories including length, weight, temperature, area, volume, speed, time, and data. It uses base-unit normalization with algorithms like the 1024-based byte system for data sizes and dedicated formulas for temperature conversions between Celsius, Fahrenheit, and Kelvin. Running entirely in your browser, it guarantees privacy by processing all calculations locally without uploading data. For additional calculations, consider using related tools such as the percentage-calculator and bmi-calculator.
How to Use Unit Converter
- Select the measurement category from length, weight, temperature, area, volume, speed, time, or data.
- Enter the value you want to convert.
- Choose the source unit and the target unit within the selected category.
- The tool calculates the converted value instantly with 2-decimal rounding.
- Review or copy the result for your use.
How It Works
The Unit Converter operates by normalizing units to a base unit for each category. For example, length units are normalized to meters, weight units to kilograms, and data units to bytes using a 1024-based system. The conversion formula applied is result = (value × fromFactor) / toFactor, ensuring precise conversions between any units in the same category.
Temperature conversions use dedicated formulas pivoting on Celsius: Fahrenheit is converted using (°C × 9/5) + 32 and Kelvin using °C + 273.15, handling the non-linear relationships accurately.
Example
Input: 5000 mg to st (stones) in weight category
Calculation:
- Normalize 5000 mg to kg: 5000 mg × 1e-6 = 0.005 kg
- Convert kg to stones: 0.005 kg / 6.35029 = 0.00079 st
Output: 0.00079 st (rounded to 0.00 st)When to Use Unit Converter

Frequently Asked Questions
How does the Unit Converter handle temperature conversions differently?
Temperature conversions use specific formulas pivoting on Celsius. For example, Fahrenheit is calculated as (°C × 9/5) + 32 and Kelvin as °C + 273.15 instead of using direct multiplication factors, due to the non-linear nature of temperature scales.
Is my data uploaded when using the Unit Converter?
No, all conversions are processed entirely on your client-side browser using JavaScript. This means none of your input values or results are uploaded or stored externally, ensuring complete privacy.
What is the base unit for data conversions in this tool?
Data conversions use the byte as the base unit, applying a 1024-based factor system. For instance, 1 KB equals 1024 bytes, and scaling continues up to petabytes (PB), following binary prefixes.
Can I convert between any units within a category?
Yes, the tool supports conversions between all supported units within each category by normalizing values to a base unit, then converting to the target unit with high precision and 2-decimal rounding.
How accurate are the conversion results?
Results are rounded to two decimal places for readability but maintain high precision internally. Base factors and formulas use standard scientific constants and internationally accepted conversion rates.
Can this tool convert time units like milliseconds to years?
Yes, time conversions normalize all units to seconds as the base unit. For example, milliseconds (ms) are converted to seconds by dividing by 1000, and years are calculated using the average length of 365.25 days.
