Formula notes
Common conversions include C = (F - 32) x 5/9, F = C x 9/5 + 32, and K = C + 273.15.
Worked examples
- Example: 25 C equals 77 F and 298.15 K.
- A laboratory temperature of 25 C equals 77 F and 298.15 K.
How to use it

Frequently asked questions
Why do science contexts prefer Kelvin?
Kelvin is an absolute scale, which is convenient for many scientific formulas.
Is a 10 C temperature change equal to 50 F?
No. A 10 C interval equals an 18 F interval; the 32-degree offset applies only to absolute readings.
Limits and interpretation
- Temperature scales include offsets, so converting a temperature difference is not always the same as converting an absolute reading.
- Values below absolute zero are physically invalid even if a raw arithmetic conversion can be written.
