Formula

Conversion formula:
°F = (°C × 9/5) + 32

The formula comes from the two scale reference points:

  • Water freezes at 0 °C = 32 °F
  • Water boils at 100 °C = 212 °F
  • The scale ratio is (212 − 32) / 100 = 1.8 (= 9/5)

Multiplying by 9/5 and then adding 32 aligns both reference points.

Practical Examples

1
Room temperature - 22 °C
(22 × 9/5) + 32 = 71.6 °F
2
Human body temperature - 37 °C
(37 × 9/5) + 32 = 98.6 °F
3
Oven temperature - 180 °C
(180 × 9/5) + 32 = 356 °F
4
Cold winter day - -10 °C
(-10 × 9/5) + 32 = 14 °F

Frequently Asked Questions

100 °C equals 212 °F. This is the boiling point of water at standard atmospheric pressure (sea level).

0 °C equals 32 °F. This is the freezing point of water at standard atmospheric pressure.

Celsius and Fahrenheit are equal at -40°. Both scales intersect at -40 °C = -40 °F.

A quick estimate: double the Celsius value, then subtract 10% and add 32. For example, 20 °C → 40 − 4 + 32 = 68 °F (exact: 68 °F). This gives a rough result within ~1°F for typical temperatures.

Did You Know?

The Celsius scale was originally inverted - Anders Celsius set 0 as the boiling point and 100 as the freezing point. It was later reversed by other scientists after his death in 1744.
