How to convert 77°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 77.

    °C = (77 − 32) × 5/9

  3. 3

    Subtract 32

    Work out the bracket first.

    77 − 32 = 45

  4. 4

    Multiply by 5/9

    Scale the result to Celsius.

    45 × 5/9 = 25

Answer: 77°F = 25°C

How to convert Fahrenheit to Celsius

Subtract 32 from the Fahrenheit value, then divide by 1.8 (or multiply by 5/9). This time the subtraction comes first.

  • 77°F: 77 − 32 = 45, and 45 ÷ 1.8 = 25°C.
  • 350°F: 350 − 32 = 318, and 318 ÷ 1.8 = 176.67°C, which most ovens round to 180°C.
  • 14°F: 14 − 32 = −18, and −18 ÷ 1.8 = −10°C.

The formula undoes the Celsius-to-Fahrenheit one in reverse order: take away the 32-degree offset between the two zero points, then shrink the result, because a Fahrenheit degree is only 5/9 the size of a Celsius degree.

Estimating in your head

Subtract 30 and halve it works well for weather: 60°F gives 15°C (exact: 15.6°C). It gets less reliable at the extremes. For 100°F the shortcut says 35°C, but the real value is 37.8°C, a difference that matters for a fever reading.

Recipe tip: US recipes give oven temperatures in steps of 25°F, and European ovens are usually marked in steps of 10°C or 20°C. Round to the nearest mark; a few degrees either way won't change the result.
