Temperature conversion reference

Temperature Converter

Convert Celsius, Fahrenheit, and Kelvin using reference formulas, common benchmark values, and clear notes about temperature scale differences.

C to F

F = C x 9/5 + 32

F to C

C = (F – 32) x 5/9

C to K

K = C + 273.15

Common temperature examples

0 C = 32 F

Water freezing point at standard pressure.

100 C = 212 F

Water boiling point at standard pressure.

20 C = 68 F

A common comfortable room temperature.

37 C = 98.6 F

A common reference for normal human body temperature.

0 K = -273.15 C

Absolute zero on the Kelvin scale.

273.15 K = 0 C

Kelvin equivalent of the Celsius freezing point.

Temperature conversion notes

  • Celsius and Fahrenheit conversions need an offset, so they are not simple multiplication-only conversions.
  • Kelvin uses the same degree size as Celsius, but starts at absolute zero.
  • Full temperature calculator pages should include formulas, examples, tables, and FAQs for each specific conversion.
Accuracy note: temperature conversions are different from simple unit multipliers because Celsius and Fahrenheit include an offset.
