100°C to Fahrenheit

212°F

100°C = 212°F = 373.15 K

Working: (100 × 9/5) + 32 = 212

100 degrees Celsius converts to 212 degrees Fahrenheit.

To convert Celsius to Fahrenheit, multiply by 9/5 (which is 1.8) and then add 32. For 100°C: 100 × 1.8 = 180, and 180 + 32 = 212. Going the other way, subtract 32 from the Fahrenheit value and multiply by 5/9.

If you only need a rough figure, double the Celsius number and add 30 — that gives 230°F here, which is 18 degrees off the exact 212°F. The shortcut is accurate enough for weather but not for cooking or medical use.

One hundred Celsius is the boiling point of water at sea level, and it is the second of the two fixed points the scale was defined by. That is the whole design of the Celsius scale: zero and one hundred bracket the liquid range of water, which is why it converts so awkwardly to a Fahrenheit scale built on different anchors.

Frequently asked questions

What is 100 degrees Celsius in Fahrenheit?

100°C is 212°F. Multiply 100 by 1.8 to get 180, then add 32 to get 212.

What is the formula for Celsius to Fahrenheit?

°F = (°C × 9/5) + 32. Multiply the Celsius temperature by 1.8, then add 32. To reverse it, subtract 32 first and then multiply by 5/9.
