# Fahrenheit

## Temperature can be measured in a unit called Fahrenheit.

Fahrenheit is measured in degrees and symbolized with °F.

Some common Fahrenheit measurements are:

-The freezing point of water, which is 32 °F.

-The boiling point of water, which is 212 °F.

Conversion to Celsius 0°F = -17.8°C

It is very easy to convert a temperature in Fahrenheit (°F) to a temperature in Celsius (°C).

To do this we must subtract 32 from our Fahrenheit measurement, and then multiply by 5/9:

°C = (°F – 32) × 5/9

Example We will do a conversion from 86 degrees Fahrenheit (warm summer weather) to degrees Celsius:

°C = (86°F – 32) × 5/9

°C = 54 x 5/9

°C = 30

Conversion to Rankine 0°F = 459.67°R

A temperature in Rankine (°R) can be easily converted from a temperature in Fahrenheit (°F).

To do this we must simply add 459.67 to our Fahrenheit (°F) measurement

R = °F + 459.67

Example We will do a conversion from 85 degrees Fahrenheit to degrees Rankine:

°R = 85°F + 459.67

°R = 527.67

Conversion to Kelvin 0°F = 255.372 K   A temperature in Kelvin (K) can be easily converted from a temperature in Fahrenheit (°F).

To do this we must simply add 459.67 to our Fahrenheit (°F) measurement, then multiply by 5/9

K = (°F + 459.67)× 5/9

Example We will do a conversion from 85 degrees Fahrenheit to degrees Kelvin:

K = (85°F + 459.67)× 5/9

K = 544.67 x 5/9

K = 302.59
