NOTE: We've guessed that you're not using a client that supports colored tables and have tried to compensate. Low graphics mode looks much better on clients that do... we recommend switching to Netscape 3.0 or Microsoft Internet Explorer.

Units of Temperature
from fahrenheit to celsius to kelvin and back

Degrees Fahrenheit, (developed in the early 1700's by G. Daniel Fahrenheit), are used to record surface temperature measurements by meteorologists in the United States. However, since most of the rest of the world uses degrees Celsius (developed in the 18th Century), it is important to be able to convert from units of degrees Fahrenheit to degrees Celsius:

Kelvin is another unit of temperature that is very handy for many scientific calculations, since it begins at absolute zero, meaning it has no negative numbers. (Note...the word "degrees" is NOT used with Kelvin.) The way to convert from degrees Celsius to Kelvin is:

The three different temperature scales have been placed side-by-side in the chart below for comparison.
