How It Works
For Length, Weight, and Speed, conversion is done by multiplying the input by the "to base" factor of the source unit, then dividing by the "to base" factor of the target unit. Temperature uses dedicated formulas: °C to °F is (°C × 9/5) + 32; °C to K is °C + 273.15. All calculations are browser-local.
Frequently Asked Questions
How accurate are the conversions?
Conversions use up to 8 significant figures. For scientific work, verify against authoritative references, as some conversion factors are defined values (exact) while others are rounded.
Can I convert Fahrenheit directly to Kelvin?
Yes. The tool converts through Celsius internally, so any combination of the three temperature units works correctly.
Will you add more unit categories?
Yes — volume, area, data storage, pressure, and energy are planned for future updates.
