What Is Fahrenheit to Celsius Conversion?

Converting Fahrenheit to Celsius translates temperature from the imperial scale used in the United States to the metric scale used by most countries worldwide. The formula involves subtracting 32 and multiplying by 5/9, accounting for the different zero points and scale intervals of the two systems. This conversion is fundamental for international communication about weather, scientific data, and cooking temperatures.

Conversion Formula

°C = (°F − 32) × 5/9

When Do You Need This Conversion?

You need Fahrenheit to Celsius conversion when interpreting US weather reports abroad, converting American recipe temperatures for metric ovens, understanding scientific literature using Celsius, or comparing temperature data across international sources.

Frequently Asked Questions

72°F equals 22.22°C. This is considered a comfortable room temperature. To calculate: (72 - 32) × 5/9 = 40 × 5/9 = 22.22°C. Other common conversions: 32°F = 0°C, 68°F = 20°C, 98.6°F = 37°C, 212°F = 100°C.

Subtract 30 and divide by 2 for a rough estimate. For example, 80°F: subtract 30 = 50, divide by 2 = 25°C (actual: 26.7°C). This works reasonably well for everyday temperatures. For cooking temperatures, remember key benchmarks: 350°F ≈ 177°C, 400°F ≈ 204°C, 450°F ≈ 232°C.

Fahrenheit and Celsius scales read the same at -40 degrees. You can verify this: (-40 × 9/5) + 32 = -72 + 32 = -40°F. This is the only temperature at which both scales intersect. Below -40, Fahrenheit values are actually higher (less negative) than Celsius values.
