Convert Temperature

Quick Reference

Water freezes: 0°C = 32°F = 273.15K
Water boils: 100°C = 212°F = 373.15K
Absolute zero: -273.15°C = -459.67°F = 0K
Room temperature: ~20°C = ~68°F = ~293K

Supported Temperature Scales

  • Celsius (°C): The most common temperature scale used worldwide. Water freezes at 0°C and boils at 100°C.
  • Fahrenheit (°F): Primarily used in the United States. Water freezes at 32°F and boils at 212°F.
  • Kelvin (K): The base unit of thermodynamic temperature in the International System of Units (SI). 0K is absolute zero.
  • Rankine (°R): An absolute scale related to Fahrenheit, where 0°R is absolute zero.
  • Réaumur (°Ré): A historical scale where the freezing and boiling points of water are 0 and 80 degrees, respectively.
