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.
