Frequently asked questions
- What is 70 °F in Celsius?
- 70 °F equals about 21.1 °C — a comfortable room temperature in both the US and metric systems.
- Why subtract 32 first?
- Because the Fahrenheit scale puts water's freezing point at 32 °F rather than 0. Subtracting 32 lines the scales up at freezing, then multiplying by 5/9 corrects the slope.
