80 °F to Celsius.

80 °F = 26.67 °C.

°F = °C

Temperature scale in °C (top) and °F (bottom). The arrow marks this value.

What 80 °F means

80 °F is 48 °F above the freezing point of water (0 °C, 32 °F).
80 °F is 18.6 °F below the generally accepted average normal body temperature (37 °C, 98.6 °F).
80 °F is 132 °F below the boiling point of water at sea level, rounded to 100 °C (212 °F).

How to convert

Subtract 32: 80 − 32 = 48.
Multiply by 5/9: 48 × 5/9 = 26.67 °C.

To convert the other way, use the Celsius to Fahrenheit converter.

Questions people ask

What is 80 °F in °C?

80 °F is 26.67 °C.

Is 80 °F above body temperature?

No. It is 18.6 °F below it. The generally accepted average normal body temperature is 37 °C (98.6 °F).

How do I estimate 80 °F in °C in my head?

Take away 30 and halve. That gives 25 °C. The exact value is 26.67 °C, so the error is 1.7 °C.
