Unit Converter
Convert length, weight, temperature and volume between common units.
System verdict
RESULT100 C = 212 F
Temperature scales have different zero points, so conversion uses formulas rather than a simple ratio — you cannot just multiply.

What this cannot tell you
- Converts between units of the same kind — length to length, and so on. Mixing kinds is rejected.
- US customary volumes are used (a US cup and gallon differ from imperial).
How this calculation works
Pick a value and two units of the same kind. Length, weight and volume convert through a common base by ratio; temperature converts through explicit formulas, because its scales have different zero points.
What the results mean
- Same kind only
- You can convert metres to feet, but not metres to kilograms. Mixing kinds is rejected rather than producing nonsense.
- US volumes
- Cups, pints and gallons here are US customary, which differ from imperial — a US gallon is about 3.79 litres, an imperial gallon 4.55.
Frequently asked questions
Why can’t I just multiply Celsius to get Fahrenheit?
Because temperature scales start at different points. 0°C is 32°F, not 0°F, so there is an offset as well as a scale factor. The formula is °F = °C × 9/5 + 32. A converter that only multiplied would be wrong at every temperature except one.
