How 25 °C becomes 77 °F
25 °C is 25 degrees above the freezing point of water on the Celsius scale (0 °C), and 45 degrees above it on the Fahrenheit scale (32 °F).
25 degrees Celsius is exactly 77 degrees Fahrenheit. The formula is °F = °C × 9/5 + 32; with 25 °C plugged in it reads like this:
To check it in your head, double it and add 30: 25 °C gives about 80 °F, 3 °F above the exact 77.
Is 25 °C = 77 °F exact?
No rounding here: 25 °C is exactly 77 °F, because the definitions behind degrees Celsius and degrees Fahrenheit make this result a short decimal.
