Celsius to Fahrenheit formula
°F = (°C × 9/5) + 32
Multiply the Celsius value by 9/5, then add 32. Temperature scales need an offset as well as a multiplier, which is why they cannot be converted with a single ratio the way length or weight can. To go the other way, use the fahrenheit to celsius converter.
