How Do You Calculate Celsius to Fahrenheit (°C to °F)?

To calculate Celsius to Fahrenheit, multiply the Celsius temperature by 1.8 (or 9/5) and add 32: °F = (°C × 1.8) + 32. For example, 25°C room temperature is (25 × 1.8) + 32 = 77°F. For mental math: double the °C, subtract 10%, and add 32.

Frequently Asked Questions

0°C is exactly 32°F, the freezing point of water at standard atmospheric pressure.
100°C is exactly 212°F, the boiling point of water at sea level.
Standard comfortable room temperature is typically 20°C to 22°C (68°F to 71.6°F).
Average normal body temperature is 37°C (98.6°F).
Multiply °C by 2, subtract 10% of that product, and add 32. For example, 30°C: `30 × 2 = 60`; `60 - 6 = 54`; `54 + 32 = 86°F`.
Multiply temperature in Celsius by 9/5 (or 1.8) and add 32: `°F = (°C × 9/5) + 32`.
