Fahrenheit to Celsius
°C = (°F − 32) × 5/9 — type a value and see the result instantly
1 °F = −17.222 °C
⇄ Celsius → FahrenheitCelsius and Fahrenheit do not share a simple multiplier; the conversion uses a formula: °C = (°F − 32) × 5/9. The reverse is °F = °C × 9/5 + 32. For example, 70 °F = 21.111 °C and 98.6 °F = 37 °C.
Water freezes at 0 °C = 32 °F and boils at 100 °C = 212 °F; the two scales meet at −40°. Normal body temperature is 37 °C ≈ 98.6 °F, and room temperature 20–22 °C ≈ 68–72 °F.
Celsius is defined by the freezing (0 °C) and boiling (100 °C) points of water; Fahrenheit by 32 °F and 212 °F. The scales cross at −40°. US weather forecasts and oven settings use Fahrenheit.
