Convert temperature, degrees Fahrenheit to degrees Celsius and show solution with steps.

Fahrenheit °F to Celsius °C Formula

°C equals °F minus 32, divided by 9/5.

°C = (°F - 32) ÷ 9/5

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

°C = (°F - 32) ÷ 1.8

How to Convert Fahrenheit to Celsius

Subtract 32 from degrees Fahrenheit
Divide the result by 1.8 (or 9/5)

For example, to convert 75 degrees Fahrenheit to Celsius (centigrade), we plug our numbers into the formula as shown below:

°C = (°F − 32) ÷ (9/5)

°C = (75 − 32) ÷ (9/5)

°C = 43 ÷ 1.8

°C = 23.89

75 degrees Fahrenheit is equal to 23.89 degrees Celsius.

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