NOTE: The grad is a unit of measure where 100 grads equal 90 degrees. It is sometimes
referred to as a 'grade' or a 'gon'.
The rev is a unit of measure which is equal to one 'revolution' or 360 degrees.
For easy readibility, the answers are displayed in a "significant figure" format which
"neatens up" answers such as 77.3333333333333333.
Numbers larger
than 1,000 will be displayed in scientific notation (and the same number of
significant figures). You may change the significant figures displayed by
changing the number in the box above.
Internet Explorer and most other browsers, will display the answers properly but
there are a few browsers that will show no output whatsoever. If so, enter a zero
in the box above. This eliminates all formatting but it is better than seeing no
output at all.
