Questions
How do I convert Celsius to Fahrenheit?
Multiply by 9/5 (or 1.8) and add 32. 20 °C × 1.8 + 32 = 68 °F. To go back, subtract 32 and multiply by 5/9: (68 − 32) × 5/9 = 20 °C.
Is there a temperature that is the same in Celsius and Fahrenheit?
Yes: −40. It is the one point where the two scales meet.
What is normal body temperature?
About 37 °C, or 98.6 °F, though a healthy range is roughly 36.1 to 37.2 °C (97 to 99 °F) and it changes through the day.
How do I convert to Kelvin?
Add 273.15 to the Celsius temperature. Kelvin has no degree sign and no negative values: 0 K is absolute zero, −273.15 °C.
Is it free? Do I need an account?
It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
