How to Convert Fahrenheit to Celsius

Formula

°C = (°F − 32) × 5/9

Worked Example

Example: 212 °F = (212 − 32) × 5/9 = 100 °C

Subtract 32 from the Fahrenheit value and multiply by 5/9 to get the Celsius equivalent.

About These Units

°F

Fahrenheit

Fahrenheit is a temperature scale where 32°F is the freezing point of water and 212°F is the boiling point of water at standard atmospheric pressure. It is primarily used in the United States and a few other countries for weather, cooking, and body temperature.

History

The Fahrenheit scale was proposed by German-Polish physicist Daniel Gabriel Fahrenheit in 1724. He originally calibrated his scale using three reference points: 0°F for a brine solution, 32°F for the freezing point of water, and 96°F for body temperature (later revised to 98.6°F).

°C

Celsius

Celsius is a temperature scale where 0°C is the freezing point of water and 100°C is the boiling point of water at standard atmospheric pressure. It is used by most countries worldwide for everyday temperature measurement and in scientific contexts.

History

The Celsius scale was proposed by Swedish astronomer Anders Celsius in 1742. Originally, his scale was inverted (0° was boiling, 100° was freezing), but it was reversed after his death. The scale was renamed from 'centigrade' to 'Celsius' in 1948 by the General Conference on Weights and Measures.

How these conversions work

Each category converts first through a base unit, then into the destination unit. That keeps the math consistent across metric and imperial systems and makes it easier to explain how results are generated.

When to double-check

Use these tools for planning, study, and everyday reference. For regulated, medical, engineering, or procurement work, confirm requirements against the official standard or specification you are working from.
