Celsius to Fahrenheit converter
1 Celsius (°C) = 33.8 Fahrenheit (°F)
How to convert Celsius to Fahrenheit
To convert Celsius to Fahrenheit, multiply by 9/5 (1.8) and add 32: °F = °C × 1.8 + 32. To go back, subtract 32 and multiply by 5/9: °C = (°F − 32) × 5/9. Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F). Normal body temperature is about 37 °C (98.6 °F), and −40 is the same in both scales.
A rough mental shortcut for weather: double the Celsius and add 30. 20 °C → about 70 °F (exact: 68 °F).
