15°C to Fahrenheit
How to Convert 15°C to Fahrenheit
-
Multiply °C by 9/5:
15 × 9/5 = 27 -
Add 32 to get °F:
27 + 32 = 59°F

Celsius to Fahrenheit — The Formula
The Celsius and Fahrenheit scales share the same physical reference points but use different zero points and step sizes. Fahrenheit degrees are smaller: one degree Celsius equals 1.8 °F, and the two scales cross at −40°.
The Formula
°F = (°C × 9/5) + 32 · °C = (°F − 32) × 5/9
For 15°C: multiply by 9/5 first, then add 32 to reach 59°F. To reverse — converting 59°F back to Celsius — subtract 32 and multiply by 5/9.
Kelvin
The Kelvin scale starts at absolute zero (−273.15 °C). Add 273.15 to any Celsius value to get Kelvin: 15 + 273.15 = 288.15 K. Kelvin is used in scientific contexts where negative temperatures make no physical sense.
15 °C is a cool temperature, common in mild or transitional seasons.
