How to convert celsius to fahrenheit
°F = °C × 9/5 + 32.
Temperature scales have different zero points, so a multiplier alone is insufficient. This page converts temperatures, not temperature differences.
Worked example
20 °C = 68 °F. To reverse it, enter the unrounded output and select Swap units. Round only the final result; converting an already-rounded result back may not reproduce the original exactly.
