How 100 °C becomes 212 °F
100 °C is 100 degrees above the freezing point of water on the Celsius scale (0 °C), and 180 degrees above it on the Fahrenheit scale (32 °F).
100 degrees Celsius is exactly 212 degrees Fahrenheit. The formula is °F = °C × 9/5 + 32; with 100 °C plugged in it reads like this:
To check it in your head, double it and add 30: 100 °C gives about 230 °F, 18 °F above the exact 212.
Is 100 °C = 212 °F exact?
No rounding here: 100 °C is exactly 212 °F, because the definitions behind degrees Celsius and degrees Fahrenheit make this result a short decimal.
