25°C to Fahrenheit

77°F

25°C = 77°F = 298.15 K

Working: (25 × 9/5) + 32 = 77

25 degrees Celsius converts to 77 degrees Fahrenheit.

To convert Celsius to Fahrenheit, multiply by 9/5 (which is 1.8) and then add 32. For 25°C: 25 × 1.8 = 45, and 45 + 32 = 77. Going the other way, subtract 32 from the Fahrenheit value and multiply by 5/9.

If you only need a rough figure, double the Celsius number and add 30 — that gives 80°F here, which is 3 degrees off the exact 77°F. The shortcut is accurate enough for weather but not for cooking or medical use.

Twenty-five degrees is a warm summer day and the upper edge of what most people find comfortable indoors without air conditioning. It is also the standard reference temperature for a great many chemical and electronic specifications, which quote values 'at 25°C' as a default condition.
