15°C to Fahrenheit

59°F

15°C = 59°F = 288.15 K

Working: (15 × 9/5) + 32 = 59

15 degrees Celsius converts to 59 degrees Fahrenheit.

To convert Celsius to Fahrenheit, multiply by 9/5 (which is 1.8) and then add 32. For 15°C: 15 × 1.8 = 27, and 27 + 32 = 59. 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 60°F here, which is 1 degrees off the exact 59°F. The shortcut is accurate enough for weather but not for cooking or medical use.

Fifteen degrees is a cool but comfortable outdoor temperature, and it is the standard reference temperature for a great deal of engineering: fuel volumes, gas measurements, and tyre pressures are frequently specified at 15°C precisely because it sits near the global average.

Frequently asked questions

What is 15 degrees Celsius in Fahrenheit?

15°C is 59°F. Multiply 15 by 1.8 to get 27, then add 32 to get 59.

What is the formula for Celsius to Fahrenheit?

°F = (°C × 9/5) + 32. Multiply the Celsius temperature by 1.8, then add 32. To reverse it, subtract 32 first and then multiply by 5/9.
