Celsius °C to Fahrenheit °F Formula

°F equals °C multiplied by 9/5, plus 32.

°F = °C * 9/5 + 32

Formula to convert Celsius to Fahrenheit F = C x 9/5 + 32

Alternatively, since 9/5 = 1.8 we can say °F equals °C multiplied by 1.8, plus 32.

°F = °C * 1.8 + 32

Formula to convert Celsius to Fahrenheit F = C x 1.8 + 32

How to Convert Celsius to Fahrenheit

Multiply degrees Celsius by 1.8 (or 9/5)
Add 32 to the product from step 1

For example, to convert 21.5 degrees Celsius (centigrade) to degrees Fahrenheit, we plug our numbers into the formula as shown below:

°F = (°C × (9/5)) + 32

°F = (21.5 × (9/5)) + 32

°F = (21.5 × 1.8) + 32

°F = 38.7 + 32

°F = 70.7

21.5 degrees Celsius is equal to 70.7 degrees Fahrenheit.

This calculator will show the steps to solve the °C to °F formula so you know how make the conversion yourself.
