Frequently Asked Questions

What is the formula for Celsius to Fahrenheit?
Fahrenheit = Celsius × 9/5 + 32. To convert the other way, subtract 32 from the Fahrenheit value and multiply by 5/9.
What are common reference temperatures in both scales?
Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at sea level. Normal body temperature is about 37 °C (98.6 °F).
Why do the two scales have different zero points?
Fahrenheit set 0 at the freezing point of a saltwater mixture and 96 near body temperature. Celsius set 0 at the freezing point of pure water and 100 at its boiling point, which is why they do not line up.
