Convert between Celsius and Fahrenheit In the United States, temperature is measured using the Fahrenheit scale. On this scale 32º is the frezzing point of the water, and 212º is the boiling point. Other countries use the Celsius scale, where 0º is the frezzing point, and 100º is the boiling point. To convert temperature given in Fahrenheit to Celsius, follow this formula: To convert temperature given in Celsius to Fahrenheit, follow this formula:

If it is 86º F, find the temperature in Celsius.

It is 30º C

If it is 40º C, find the temperature in Fahrenheit.

It is 104º F.
