How to convert 80°F to °C

Follow these steps to check the answer yourself.

  1. 1

    Write the conversion formula

    To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9.

    °C = (°F − 32) × 5/9

  2. 2

    Substitute the Fahrenheit value

    Replace °F with 80.

    °C = (80 − 32) × 5/9

  3. 3

    Subtract 32

    Work out the bracket first.

    80 − 32 = 48

  4. 4

    Multiply by 5/9

    Scale the result to Celsius.

    48 × 5/9 = 26.67

Answer: 80°F = 26.67°C

Is 80°F hot or cold?

80°F (26.67°C) reads as warm on the thermometer: pleasant summer weather. Typical context: warm summer weather.

80°F is 12°F warmer than typical room temperature (68°F), and 18.6°F cooler than average human body temperature (98.6°F).

Quick mental math

To estimate Fahrenheit to Celsius in your head, subtract 30 from the Fahrenheit value and halve it.

(80 − 30) ÷ 2 = 25°C (exact answer: 26.67°C)

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 Celsius to Fahrenheit converter: 26.67°C converts back to 80°F.

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.
