Dimensional Analysis

• Arrange conversion factors so the starting unit cancels.
• Arrange conversion factors so the starting unit is on the bottom of the conversion factor.
• May string conversion factors
• We do not need to know every relationship, as long as we can find something else to which the starting and desired units are related.

Given unit × (find unit/given unit) = find unit

• Example
• 2.00 ft × (12 in/1 ft) = 24.0 inches
