Celsius to Fahrenheit Converter
Formula
°F = (°C × 9/5) + 32
To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9/5 (or 1.8), then add 32. This formula accounts for the different starting points and scale sizes of the two temperature systems. The Celsius scale sets water's freezing point at 0° and boiling point at 100°, while Fahrenheit uses 32° and 212° respectively.
Frequently Asked Questions
What is 0°C in Fahrenheit?
0°C equals 32°F. This is the freezing point of water.
What is 100°C in Fahrenheit?
100°C equals 212°F. This is the boiling point of water at standard atmospheric pressure.
At what temperature are Celsius and Fahrenheit equal?
-40 degrees is the same in both scales. -40°C = -40°F.
Why does the US use Fahrenheit?
The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724 and was widely adopted in English-speaking countries. While most countries switched to Celsius as part of metrication, the US retained Fahrenheit for everyday use.
What is normal body temperature in both scales?
Normal human body temperature is approximately 37°C or 98.6°F, though it can vary slightly between individuals.
