About This Converter
This tool helps you convert measurements across the most common categories — length, mass, temperature, area, volume, speed, time, and digital storage — using precise conversion factors and clear formatting. Everything runs in your browser, so your inputs never leave your device.
How conversions work
- Factor-based units (e.g., metres → feet, kilograms → pounds) use a base unit and scale factors for accuracy.
- Temperature uses dedicated formulas (Celsius, Fahrenheit, Kelvin) rather than scale factors.
- Time is normalised through seconds; Digital storage supports both SI (kB, MB) and binary (KiB, MiB) units.
Quick tips
- Use the Swap button to quickly reverse your conversion.
- Try pasting values like
10 km
,5ft
, or2 MiB
— the parser will detect units. - Copy the result to share or document your calculation.
