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

Practical Examples
A comfortable room temperature of 72°F converts to about 22.2°C, helpful when adjusting a thermostat labeled in Celsius. If an American recipe says to preheat the oven to 350°F, that equals approximately 176.7°C, a standard baking temperature in metric countries. A fever of 101°F translates to about 38.3°C, the threshold many international clinics use. On a hot summer day when it hits 100°F, that is roughly 37.8°C — useful context when reading weather reports from countries using the Celsius scale.
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.
