How to Convert Fahrenheit to Celsius

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature and multiply by 5/9: °C = (°F − 32) × 5/9.

For example, 72°F: (72 − 32) × 5/9 = 22.22°C. Room temperature in the US (72°F) equals about 22°C.

The Fahrenheit scale is primarily used in the United States, while Celsius is used in virtually every other country.

Key Temperature Reference Points

32°F = 0°C (Water freezes)
72°F = 22.2°C (Room temperature)
98.6°F = 37°C (Body temperature)
212°F = 100°C (Water boils)
-40°F = -40°C (Scales meet)

Memorizing these key points helps you quickly estimate temperatures without a calculator.

Quick Mental Conversion Trick

For a rough estimate: subtract 30 from the Fahrenheit temperature and divide by 2. For example, 80°F: (80 − 30) ÷ 2 = 25°C (actual: 26.7°C).

This shortcut is accurate enough for everyday use like checking weather forecasts or setting an oven.

Frequently Asked Questions

What is 100°F in Celsius?

100°F equals 37.78°C. This is slightly above normal body temperature (37°C / 98.6°F).

At what temperature are Fahrenheit and Celsius the same?

Fahrenheit and Celsius are equal at -40 degrees. This is the only point where both scales intersect.

Why does the US use Fahrenheit?

The US adopted the Fahrenheit scale in the colonial era and never switched to Celsius. Most other countries transitioned to Celsius as part of metric system adoption.
