°F = °C × 1.8 + 32

A Fahrenheit degree is smaller than a Celsius degree: 1 °C equals 1.8 °F (9/5). The scales also start in different places, since water freezes at 0 °C but at 32 °F. So multiply by 1.8, then add 32. A quick check: 20 °C, a comfortable room, is 68 °F.

  1. Multiply by 1.8 (that is 9/5) 20 × 1.8 = 36
  2. Add 32 36 + 32 = 68 °F
