Common Celsius and Fahrenheit Temperatures
A handy reference for everyday temperatures, with examples that make the two scales easier to compare.
In this guide
A few useful reference points
0°C is 32°F, 20°C is 68°F, 25°C is 77°F, 30°C is 86°F and 100°C is 212°F. These points are useful for a quick sense check even when you do not have a calculator.
Why the scales feel different
Celsius and Fahrenheit use different zero points and different size increments. A change of 1°C equals a change of 1.8°F, so the numbers do not move at the same rate.
For weather
When reading a weather report, the most useful skill is often recognising the general range rather than memorising every conversion. Over time, reference temperatures become familiar.
For technical work
Use the exact conversion when a measurement affects a process or specification. A rough mental conversion is useful for everyday decisions but should not replace the required engineering or scientific value.
