## How does the temperature converter work?

Fahrenheit and Celsius are related through a so called *linear relationship*. The formula is different depending on whether you're converting from Fahrenheit to Celsius or Celsius to Fahrenheit

#### Converting from Fahrenheit to Celsius

In order to convert from Fahrenheit to Celsius we simply subtract 32 and multiply by 5/9. That is, °C = (°F - 32) · (5/9).

Let's try an example: What is 32° Fahrenheit in Celsius? Well (32 °F - 32) · (5/9) = (0) · (5/9) = 0 °C. Admittedly we chose a pretty convenient number as 32 °F becomes a nice and round 0 °C.

#### Converting from Celsius to Fahrenheit

In order to convert from Celsius to Fahrenheit we simply multiply by 9/5 and add 32. That is, °F = (9/5) · °C + 32.

For example, if we wanted to see what 0° Celsius is in Fahrenheit we simply plug in 0 in this formula: (9/5) · 0 + 32 = 0 + 32 = 32 °F. This is fortunately what we expected as our previous example showed that 32 °F = 0 °C.
