An important part of baking and candy making is starting off with the right temperature. Knowing how to do temperature conversions is very helpful when you are reading a recipe from a book printed in a different country. Baking and candy making use very precise measurements, and a couple of degrees off can mean the item being underbaked or boiled for too long. Here are basic steps to convert Celsius and Fahrenheit temperatures.

Celsius to Fahrenheit:
Basic Formula (C*9)/5+32 = F

An example:
10 degrees C x 9 = 90
90 / 5 = 18
18 + 32 = 50
So, 10 degrees Celsius equals 50 degrees Fahrenheit.

Fahrenheit to Celsius:
Basic Formula (F - 32)*5/9 = C

An example:
50 degrees Fahrenheit - 32 = 18
18 x 5 = 90
90 / 9 = 10
So, 50 degrees Fahrenheit equals 10 degrees Celsius.

This is simple algebra, so if you take the steps one at a time you'll have the right answer each time. Don't worry if you don't have an even number at the end. Round up or down to the closest degree.
