Temperature conversions are common, but you can't always look at a thermometer that lists degrees in both Celsius and Fahrenheit. However, all you need to convert between the two is a simple formula.

## Conversion Formula

The formula for converting a measurement in Celsius to Fahrenheit is:

F = 1.8C+ 32

where F is the temperature in degrees Fahrenheit and C is the temperature in degrees Celsius.

The formula may also be written as:

F = 9/5C+ 32

It is easy to convert Celsius to Fahrenheit by following these two steps:

- Multiply your Celsius measurement by 1.8.
- Add 32 to the result.

The final answer will be the temperature in degrees Fahrenheit.

Note: If you are doing temperature conversions for a homework problem, take care to report the converted value using the same number of significant digits as the original number.

## Example

Imagine, for example, that while traveling in Europe you come down with an illness. You only have access to a thermometer with Celsius measurements, which tells you that your body temperature is 37 degrees. You want to convert this measurement to Fahrenheit.

To do this, plug the temperature measurement into the equation:

F = 1.8 C + 32

F = (1.8)(37) + 32

F = 66.6 + 32

F = 98.6

The original value, 37 degrees Celsius, has two significant digits, so the Fahrenheit temperature should be reported as 99 degrees Fahrenheit.
