To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9. This conversion is essential for Americans traveling to metric countries, understanding international weather forecasts, converting cooking temperatures from American recipes, and interpreting scientific data that uses Celsius.

## Formula

°C = (°F − 32) × 5/9

## Units

### Fahrenheit (°F)

A temperature scale where 32°F is the freezing point and 212°F is the boiling point of water. Primarily used in the United States.

### Celsius (°C)

A metric temperature scale where 0°C is the freezing point and 100°C is the boiling point of water. Used worldwide except in the US.

## Background

When an American sees a European weather forecast of 35°C, they need to know that's a scorching 95°F. Conversely, a comfortable 72°F room temperature is about 22°C. Medical professionals in the US use Fahrenheit (fever threshold: 100.4°F), while the rest of the world uses Celsius (fever threshold: 38°C). This conversion bridges the gap.

## Good to Know

When Americans move abroad, learning to think in Celsius is one of the biggest daily adjustments. Key benchmarks to memorize: 0°C = freezing, 20°C = room temp, 37°C = body temp, 100°C = boiling.

## FAQ

### What is the formula for Fahrenheit to Celsius?

The formula is: °C = (°F − 32) × 5/9. For example, 72°F: (72 − 32) × 5/9 = 22.2°C. A quick shortcut: subtract 30, then divide by 2 for a rough estimate.

### What is 32 degrees Fahrenheit in Celsius?

32°F equals exactly 0°C - the freezing point of water. This is the baseline for the conversion formula.

### What is 98.6°F in Celsius?

98.6°F equals exactly 37°C - normal human body temperature. This is one of the most commonly referenced Fahrenheit-to-Celsius conversions in medicine.

### What is room temperature in both Fahrenheit and Celsius?

Room temperature is typically 68-72°F, which equals 20-22°C. A thermostat set to 70°F is approximately 21.1°C.

## Non-Frequently Asked Questions

### Did Fahrenheit invent heat?

No. Daniel Gabriel Fahrenheit invented a mercury thermometer and a temperature scale. Heat existed for roughly 13.8 billion years before he came along in 1714.

### Is 0 Fahrenheit the coldest anything can get?

Not even close. Fahrenheit set 0 degrees at the coldest temperature he could create with an ice-salt mixture. Absolute zero is minus 459.67 degrees Fahrenheit. Space is about minus 455 degrees Fahrenheit. His zero was just a really cold day in Danzig.

### If I move to Europe, will I feel temperatures differently?

You will feel exactly the same temperatures. You will just be confused about the numbers. 20 degrees Celsius sounds cold to an American but is actually a pleasant spring day. Your body does not care what number is on the sign.
