Handy Units
Celsius to Fahrenheit°C → °F
Formula: °F = °C × 9/5 + 32
Formula
°F = °C × 9/5 + 32
Example: 30 °C = 86 °F
Temperature scales start from different zero points, so converting is more than multiplying: shift to a common zero (absolute zero, in kelvin), then scale by the size of a degree. That’s why 0 °C is 32 °F, not 0 °F.
