How to convert 20 °C to °F
Use the formula °F = (°C × 9/5) + 32 and substitute 20 for °C:
°F = (20 × 9/5) + 32°F = 36 + 32°F = 68
So 20 °C = 68 °F.
What does 20 °C mean?
Twenty degrees Celsius is a common reference for “room temperature” in science and in everyday use, and a comfortable indoor setting for most people.
20 °C is in the range usually described as room temperature — comfortable indoors and a pleasant warm day outside.
- Fahrenheit
- 68 °F
- Kelvin
- 293.15 K
- Quick estimate (double + 30)
- 70 °F
For 20 °C the quick “double it and add 30” estimate gives 70 °F — 2 °F too high. The shortcut works best between about 0 °C and 20 °C; use the exact formula for anything that matters.

The Celsius to Fahrenheit formula
°F = (°C × 9/5) + 32
Multiply the Celsius temperature by 9/5 (1.8) because a Celsius degree is 1.8 times larger than a Fahrenheit degree, then add 32 because water freezes at 32 °F rather than 0 °F. To go the other way, use °C = (°F − 32) × 5/9 — for example, 68 °F back to Celsius gives 20 °C.
