Equivalence

 An equivalent is a statement of fact relating one unit to another. Examples: Equivalents 12 inches equals 1 foot (or 12 inches = 1 foot) 5,280 feet equals 1 mile (or 5,280 feet = 1 mile) 60 seconds equals 1 minute (or 60 seconds = 1 minute) An equivalent can be written as 2 rates called conversion factors.
Example Equivalents and their Two Conversion Factors
 Equivalent (Statement of fact) --> Conversion Factor 1 OR Conversion Factor 2 12 inches = 1 foot --> 12 inches / foot OR 1 foot per 12 inches 1foot / 12 inches 5280 feet = 1 mile --> 5280 feet per 1 mile 5280 feet / 1 mile OR 1 mile per 5280 feet 1 mile / 5280 feet 60 sec. = 1 min. --> 60 sec. per 1 min. 60 sec. / 1 min. OR 1 min. per 60 sec. 1 min./60 sec.

Note:
In the English System, there's no pattern to the numbers in the equivalents. (Look in above table at the numbers: 12, 5280, 60.) That's why scientists don't use the English System. They use the metric system, which we'll get to. I'm using the English System for now because we're more familiar with it.
