Converting 100°C (Water Boiling Point) to Fahrenheit

Converting boiling temperature from Celsius to Fahrenheit.

Inputs: Source Temperature: 100 °C, Target Unit: Fahrenheit (°F)
Result: 212.0 °F

(100 × 9/5) + 32 = (100 × 1.8) + 32 = 180 + 32 = 212.0 °F.

How to Use This Tool

  1. Enter the numerical temperature reading in the input box.
  2. Select your starting temperature unit (°C, °F, K, or °R).
  3. Select your destination temperature unit.
  4. View the converted temperature reading and the exact formula steps.
