Calculation
- (25 × 9 ÷ 5) + 32 = 77 °F
Formula
°F = (°C × 9 / 5) + 32
Worked examples
Body temperature
(37 × 9 ÷ 5) + 32
= 98.6 °F
Freezing point of water
(0 × 9 ÷ 5) + 32
= 32 °F
Warm summer day
(30 × 9 ÷ 5) + 32
= 86 °F
How the conversion works
A Celsius degree is 1.8 times larger than a Fahrenheit degree, so the Celsius value is multiplied by 9/5. The two scales also start at different points — water freezes at 0 °C but 32 °F — so 32 is added afterwards.
