Converting Fahrenheit to Celsius

Temperature scales do not share a zero point, so converting between them needs both a scale factor and an offset rather than a single multiplier. This calculator converts through kelvin, the SI base unit.

The usual formulas

  • °F = °C × 9/5 + 32
  • °C = (°F − 32) × 5/9
  • K = °C + 273.15
  • °R = (°F + 459.67)
