What is 72°F in Celsius?

72°F equals about 22°C — a comfortable room temperature.

Is there a quick way to estimate F to C?

Subtract 30, then divide by 2. Example: 80°F → (80-30)/2 = 25°C (actual: 26.7°C). Good for quick estimates!

Why does the US use Fahrenheit?

Historical reasons. The US adopted Fahrenheit before Celsius became the global standard. Most of the world now uses Celsius.

Convert Fahrenheit to Celsius

Converting Fahrenheit to Celsius involves a special calculation due to the offset-based nature of temperature scales. This conversion is essential for understanding American weather reports, following US recipes, and medical temperature readings. Understanding how to convert between these units is important when working with thermostats, scientific calculations, and international communication. Whether you're traveling internationally, following recipes, or working with scientific data, knowing this conversion is invaluable for accurate measurements and clear communication across different systems.

Fahrenheit (°F)

Celsius (°C)

Quick Answer: 32°F = 0°C (freezing), 68°F = 20°C (room temp), 98.6°F = 37°C (body temp), 212°F = 100°C (boiling).

Convert Celsius to Fahrenheit

How the Conversion Works

°C = (°F - 32) × 5/9

To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit temperature, then multiply by 5/9 (or divide by 1.8). For example, 72°F: (72 - 32) × 5/9 = 22.22°C. For a quick estimate, subtract 30 and divide by 2. This works well for temperatures between 32°F and 100°F.
