How to Convert Fahrenheit to Celsius

°C = (°F - 32) × 5/9

32°F = 0°C (freezing point of water)
212°F = 100°C (boiling point of water)

Example: convert 72°F to °C:
(72 - 32) × 5/9 = 40 × 5/9 = 22.22°C

About the Units

Fahrenheit (°F)

The Fahrenheit scale was proposed by Daniel Gabriel Fahrenheit in 1724. On this scale, water freezes at 32°F and boils at 212°F at standard atmospheric pressure. It is primarily used in the United States, its territories, and a few Caribbean nations for everyday temperature measurement including weather forecasts, cooking, and body temperature.

Celsius (°C)

The Celsius scale, originally called centigrade, was devised by Anders Celsius in 1742. Water freezes at 0°C and boils at 100°C, creating a clean 100-degree interval. It is the standard temperature scale used worldwide in science, industry, and daily life in virtually every country except the United States.

Frequently Asked Questions

What is 72°F in Celsius?

72°F equals 22.22°C. This is calculated using the formula: (72 - 32) × 5/9 = 22.22°C. It is considered a comfortable room temperature.

How to convert Fahrenheit to Celsius?

To convert °F to °C, subtract 32 from the Fahrenheit value, then multiply the result by 5/9. Formula: °C = (°F - 32) × 5/9.

What is the formula for F to C?

The formula is: °C = (°F - 32) × 5/9. You can also write it as °C = (°F - 32) / 1.8, since 9/5 = 1.8.

What is 98.6°F in Celsius?

98.6°F equals exactly 37°C. This is the average normal human body temperature. Calculation: (98.6 - 32) × 5/9 = 37°C.

What is 32°F in Celsius?

32°F equals 0°C. This is the freezing point of water at standard atmospheric pressure.

What is 350°F in Celsius?

350°F equals 176.67°C. This is one of the most common oven temperatures used for baking cakes, cookies, and casseroles.

Why does the US use Fahrenheit?

The US adopted Fahrenheit before the metric system became widespread. While most countries switched to Celsius, the US retained Fahrenheit due to tradition, the cost of changing, and public familiarity with the scale.

What temperature is the same in F and C?

-40 degrees is the same on both scales. At -40°F = -40°C. This is the only point where the two scales intersect.

Is 0°F colder than 0°C?

Yes, 0°F is much colder than 0°C. 0°F equals -17.78°C, while 0°C equals 32°F (the freezing point of water).

Quick way to estimate F to C?

A quick mental math trick: subtract 30, then divide by 2. For example, 72°F: (72 - 30) / 2 = 21°C (actual: 22.22°C). It is not exact but gives a close approximation.
