This degrees Celsius to degrees Fahrenheit converter turns any °C reading into °F instantly, in your browser, with the formula shown so you can check the result by hand. Degrees Celsius are part of the metric system used in most countries; degrees Fahrenheit are a US customary unit. Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at sea level.
The formula is °F = °C × 9/5 + 32. For a quick mental estimate between Celsius and Fahrenheit, double the Celsius value and add 30; it is within a few degrees for everyday temperatures. Normal body temperature is 37 °C, which is 98.6 °F.

Frequently asked questions
How many degrees Fahrenheit are in 20 degrees Celsius?
20 °C = 68 °F. Apply the formula °F = °C × 9/5 + 32. The converter on this page does the same arithmetic for any value, including decimals.
What is the formula to convert degrees Celsius to degrees Fahrenheit?
°F = °C × 9/5 + 32. Temperature scales have different zero points, so you cannot simply multiply; the offset matters. Worked example: 100 °C = 212 °F.
Is -10 °C the same as 14 °F?
Yes. -10 °C = 14 °F, a common winter temperature. Notice that -40 is the one point where Celsius and Fahrenheit agree: -40 °C equals -40 °F.
How do I convert degrees Fahrenheit back to degrees Celsius?
Reverse the formula: °C = (°F − 32) × 5/9. Or use the degrees Fahrenheit to degrees Celsius page linked above, which has its own table and examples.
