Temperature scales

Common temperatures

  • Water freezes: 0 °C = 32 °F = 273.15 K
  • Room temperature: 20 °C = 68 °F = 293.15 K
  • Water boils: 100 °C = 212 °F = 373.15 K

The formulas

°F = °C × 9/5 + 32
K = °C + 273.15

Kelvin starts at absolute zero, −273.15 °C, and has the same step size as Celsius. At −40 the Celsius and Fahrenheit scales meet: −40 °C is −40 °F.
