About this conversion
Temperature conversions help with American oven recipes in Fahrenheit, weather apps set to the wrong unit, and science homework that uses kelvin.
Writing the units next to every number while you work is the simplest way to avoid mistakes. If the units do not cancel to leave the one you want, the calculation is set up wrongly.
Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.
