Frequently asked questions
- What is 32 F in Celsius?
- (32 - 32) x 5/9 = 0 C, the freezing point of water.
- How do I quickly estimate Celsius from Fahrenheit in my head?
- Subtract 32, then halve the result (instead of multiplying by 5/9). This underestimates by about 10%, but it is fast — 68 F: (68-32)/2 = 18 C vs the exact 20 C.
- Why is 98.6 F considered normal body temperature?
- 98.6 F is exactly 37 C (37 x 9/5 + 32). The Celsius value was established first; the Fahrenheit equivalent is a rounded conversion.
