20 °C = 68 °F

How to convert degrees Celsius to degrees Fahrenheit

Formula: °F = °C × 1.8 + 32

Worked example: 20 °C → 20 × 1.8 + 32 = 68 °F

To estimate in your head, double the Celsius value and add 30: 20 °C gives about 70 °F (exact: 68 °F). The shortcut drifts at high temperatures, so use the exact formula for cooking. Body temperature of 37 °C is 98.6 °F, and a fever of 38 °C is 100.4 °F.

What is a degree Celsius?

The Celsius scale puts the freezing point of water at 0 °C and its boiling point at sea level at 100 °C. It is the temperature scale of almost every country outside the US, of science and of medicine. A change of one degree Celsius equals a change of one kelvin.

What is a degree Fahrenheit?

On the Fahrenheit scale, water freezes at 32 °F and boils at 212 °F, so 180 degrees separate the two points instead of 100. The United States uses it for weather, ovens and body temperature, where 98.6 °F is the classic normal value.

Frequently asked questions

How do you convert degrees Celsius to degrees Fahrenheit?

Use the formula °F = °C × 1.8 + 32. Example: 20 °C → 20 × 1.8 + 32 = 68 °F.

What is 0 °C in °F?

0 °C equals 32 °F, from the formula °F = °C × 1.8 + 32.
