Detailed Description

In each case here, given a value in the units mentioned first in the name, you should multiply by the given constant to produce the equivalent quantity measured in the units that appear second in the name.

You can perform the reverse conversion by dividing by the constant, or by using another conversion constant with the names reversed if one is supplied here.
