decimal degrees to degrees, minutes, seconds (DMS)

How can I convert from decimal degrees (as in, "degrees of longitude" or "degrees of latitude") to degrees, minutes, and seconds, or vice versa?  How can I convert from fractional hours to hours, minutes, and seconds, or vice versa?

Here are step by step instructions from the About.com website.

1. The whole units of degrees will remain the same (i.e. in 121.135 longitude, start with 121).

2. Multiply the decimal by 60 (i.e. .135 * 60 = 8.1).
The whole number becomes the minutes (8').

3. Take the remaining decimal and multiply by 60. (i.e. .1 * 60 = 6).
The resulting number becomes the seconds (6"). Seconds can remain as a decimal.

Take your three sets of numbers and put them together, using the symbols for degrees (), minutes (), and seconds (") (i.e. 1218'6" longitude)
