77°F to °C — What is 77 Fahrenheit in Celsius?

77°F = 25°C. Use the exact formula (°F − 32) × 5/9 to convert any Fahrenheit temperature to Celsius — algebraically exact with zero rounding, as defined by the NIST.

Answer

25°C

77 °F = 25 °C

Exact: 25.000000 °C · uses the BIPM-defined constant

How it's calculated

(°F − 32) × 5/9 = °C

Step 1: Apply the formula to the input value.
Step 2: (77 − 32) × 5/9 = 45 × 5/9 = 25

Common questions about 77 °F to °C

What is 77°F in Celsius?

77 degrees Fahrenheit equals exactly 25 degrees Celsius. The formula is (77 − 32) × 5/9 = 25°C. In Kelvin, this is 298.15 K.

How do you convert 77°F to °C step by step?

Step 1: Subtract 32 from 77 to get 45. Step 2: Multiply by 5/9 (or 0.5556). Result: 45 × 5/9 = 25°C. This formula is algebraically exact.

Is 77°F hot or cold?

77°F is warm and pleasant — great outdoor weather.

What is 25°C back in Fahrenheit?

25°C converts back to exactly 77°F — which is 77°F. The conversion is perfectly reversible using the inverse formula: (°C × 9/5) + 32.

What should I wear at 77°F?

At 77°F, wear light, loose clothing — shorts and a t-shirt. Stay hydrated. A hat provides useful sun protection. Cotton and moisture-wicking fabrics are ideal.
