Find the conversion factor from Degree Fahrenheit to Degree Celsius
1 °F = 0.5555555556 K · 1 °C = 1 K
factor = 0.5555555556 ÷ 1 = 0.5555555556 °C per °F
Multiply by the factor: °F cancels, leaving °C
°C = °F × (°C per °F)
1 °F × 0.5555555556 °C per °F = 0.5555555556 °C

1 °F = 0.5555555556 °C, so °C = °F × 0.5555555556

This converts a change in temperature. To convert a thermometer reading, use the Temperature converter.
