Temperature Conversion Calculator
Calculator Use. Temperature conversions are performed by using a formula, which differs depending on the two temperature scales you are converting between. For example, to convert 50 degrees Celsius (centigrade) to Fahrenheit, we plug our numbers into the formula as shown below: F = C * 9/5 + 32. F = 50 * 9/5 + 32. F = 90 + 32.
