About Fahrenheit to Celsius Conversion

Fahrenheit (°F) is a temperature scale invented by Daniel Gabriel Fahrenheit in 1724. It is the primary temperature scale in the United States and some Caribbean nations. Celsius (°C), also known as centigrade, was developed by Anders Celsius in 1742 and is used by most countries worldwide, as well as in all scientific contexts.

The two scales meet at -40°, the only temperature that reads the same in both systems. Key reference points: water freezes at 32°F (0°C) and boils at 212°F (100°C). Converting Fahrenheit to Celsius is commonly needed when traveling abroad, reading international weather forecasts, following recipes from other countries, or interpreting medical thermometer readings. The formula is: °C = (°F - 32) × 5/9.

Frequently Asked Questions

The formula is: °C = (°F - 32) × 5/9. First subtract 32, then multiply by 5/9 (or divide by 1.8).
72°F equals 22.22°C. This is considered a comfortable room temperature in most settings.
-40 degrees is where Fahrenheit and Celsius are exactly equal. -40°F = -40°C. This is a fun math fact!
Only the United States, Bahamas, Cayman Islands, Liberia, Palau, and Micronesia use Fahrenheit. The rest of the world uses Celsius.
Yes, 100°F (37.78°C) is considered a low-grade fever. Normal body temperature is about 98.6°F (37°C). A temperature of 100.4°F (38°C) or higher is typically considered a fever.
