Formula
°F = °C × 9/5 + 32. Example: 180 °C = 356 °F.
Celsius to Fahrenheit is needed for weather forecasts, oven temperatures in US recipes, fever readings (37 °C is normal body temperature, 98.6 °F) and thermostat settings. Multiply by 9/5 (1.8) and add 32. A rough mental version is "double it and add 30", which is close for everyday temperatures. The two scales meet at −40, where −40 °C equals −40 °F.
