Celsius to Fahrenheit (°C to °F) Converter

Convert Celsius temperatures to Fahrenheit with the 9/5 scale factor, 32-degree offset and practical examples.

How it works

°F = (°C × 9 ÷ 5) + 32

Celsius and Fahrenheit have different zero points as well as different degree sizes. Apply both the multiplier and the offset.

How to use this tool

Enter a Celsius temperature, including a minus sign if needed. Select Convert for the equivalent Fahrenheit reading.

Worked example

20°C × 9/5 + 32 = 36 + 32 = 68°F. Water freezes at 0°C, which converts to 32°F.

Limits of this tool

This formula is for temperature readings, not changes in temperature. Values below −273.15°C are outside the supported physical range.

Good to know

Results are computed with 64-bit floating-point numbers. Very large or tiny values can lose precision; the display rounds only after calculation. Non-finite results are rejected.
