Celsius to Fahrenheit (and Kelvin)
AllinOne Editorial · Published 2026-09-16
Temperature conversion needs an offset. 0°C is 32°F, not 0°F. This converter goes through kelvin so all three scales stay consistent.
Length and mass converters only multiply. Temperature has a zero that is not shared: ice melts at 0°C and 32°F. Skip the offset and every weather conversion is wrong.
Formulas
- K = C + 273.15
- C = (F − 32) × 5/9
- F = C × 9/5 + 32
The Temperature Converter on this site converts through kelvin so Celsius, Fahrenheit and Kelvin cannot drift apart. 20°C = 68°F = 293.15 K.
Cooking “gas mark” and older scientific scales are not included. Stick to C, F and K here.
