Degree classification in meteorological terms typically describes the units for temperature in Fahrenheit, Celsius and Kelvin. While Fahrenheit and Celsius are the most common units used to measure temperature, scientists principally use Celsius and Kelvin for their calculations. The point of zero in Kelvin is approximately minus-273 degrees Celsius, conceivably the coldest temperature that exists in our universe.

## Calculating Degrees

1. 1

Read the temperature "a" from a Fahrenheit thermometer. To obtain the temperature in degrees Celsius, subtract 32 from temperature "a," then multiply the difference by 5/9.

b = (5/9)*(a-32)

2. 2

Add 32 to Celsius temperature "b" and multiply the sum by 9/5.

a = (9/5)*b+32

3. 3

Add 273 to Celsius temperature "b" to obtain temperature "c" in Kelvins.

c= b+273

#### Tips and warnings

• If you are considering temperature for chemistry or physics, it is generally most useful to convert to Kelvins before taking on the rest of the equation.
• Be careful to only convert from Celsius to Kelvin, as Fahrenheit and Kelvin will not convert using the above equation.
