degrees Fahrenheit
How to convert degrees Celsius to degrees Fahrenheit
Multiply the Celsius temperature by 9/5 (1.8), then add 32.
Formula
°F = °C × 9/5 + 32
Examples
- 20 °C → 20 × 1.8 + 32 = 68 °F
- 37 °C → 37 × 1.8 + 32 = 98.6 °F
- 180 °C → 180 × 1.8 + 32 = 356 °F

About degrees Celsius
On the Celsius scale water freezes at 0 °C and boils at about 100 °C at sea-level pressure. Today it is formally defined from the kelvin (°C = K − 273.15). It is the scale used for weather and cooking in almost every country.
About degrees Fahrenheit
On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F, so one Fahrenheit degree is 5/9 of a Celsius degree. It is the everyday scale in the United States for weather, ovens and body temperature.
Frequently asked questions
What is the formula to convert Celsius to Fahrenheit?
°F = °C × 9/5 + 32. Multiply the Celsius temperature by 9/5 (1.8), then add 32.
What is 20 °C in Fahrenheit?
20 °C is 68 °F.
What is 37 °C in Fahrenheit?
37 °C is 98.6 °F.
What is a quick way to estimate Celsius to Fahrenheit?
Double the Celsius value and add 30. For 20 °C that gives 70 °F, close to the exact 68 °F. The estimate gets less accurate at high temperatures.
Is 37 °C a normal body temperature?
37 °C (98.6 °F) is the traditional reference value. Normal body temperature varies between people and through the day, roughly 36.1–37.2 °C.
