How to solve it
Multiply the Celsius value by 1.8 and add 32. To go the other way, subtract 32 first and then divide by 1.8.
Worked example
25 degrees Celsius gives 25 x 1.8 = 45, and 45 + 32 = 77 degrees Fahrenheit.
Common mistake
Adding 32 before multiplying. Swapping the two steps produces a very different number.
