How to convert 20°C to °F
Follow these steps to check the answer yourself.
- 1
Write the conversion formula
To convert Celsius to Fahrenheit, multiply by 9/5 and add 32.
°F = (°C × 9/5) + 32
- 2
Substitute the Celsius value
Replace °C with 20.
°F = (20 × 9/5) + 32
- 3
Multiply by 9/5
Work out the bracket first.
20 × 9/5 = 36
- 4
Add 32
Add the 32° offset to get Fahrenheit.
36 + 32 = 68
Answer: 20°C = 68°F

Is 20°C hot or cold?
20°C (68°F) reads as warm on the thermometer: pleasant summer weather. Typical context: mild weather and comfortable room temperature.
20°C is typical room temperature. On the water scale it sits 20% of the way from freezing to boiling.
Quick mental math
To estimate Celsius to Fahrenheit in your head, double the Celsius value and add 30.
20 × 2 + 30 = 70°F (exact answer: 68°F)
The shortcut is close for everyday temperatures but drifts further from the exact answer in very hot or very cold conditions.
To go the other way, use the Fahrenheit to Celsius converter: 68°F converts back to 20°C.

Good to know
- Anders Celsius proposed his scale in 1742. It was originally inverted, with 0 for boiling water and 100 for freezing; the order was flipped soon after his death.
- Daniel Gabriel Fahrenheit introduced his scale in 1724. The United States and a handful of other countries still use it for everyday temperatures.
- -40 is the only temperature that reads the same in Celsius and Fahrenheit.
- A change of 1°C or 1 K equals a change of 1.8°F.
