Convert Celsius (°C) to Fahrenheit (°F)
Convert Celsius (°C) to Fahrenheit (°F): multiply by 9/5 and add 32, so 20 °C is 68 °F. Turns the metric temperature scale used worldwide into the Fahrenheit scale used in the US.
Formula
1 °C = 33.8 °F

About °C to °F
The formula is °F = °C × 9/5 + 32. Unlike most conversions this has an offset, not just a factor, because the scales start at different points (0 °C = 32 °F, the freezing point of water). The two scales meet at minus 40 degrees.
It's handy for weather, cooking and travel between metric countries and the US. Quick anchors: 0 °C = 32 °F (freezing), 37 °C is about 98.6 °F (body temperature), and 100 °C = 212 °F (boiling).
