Changing one unit scale to a different unit scale.
Example: Changing feet to inches. 1 ft to 12 inches (or ). Both feet and inches are units of distance. kg ≠ ft
New example: How tall is a 2.17 meter high ceiling when measured in feet?
The way to convert/change this value to feet is by using a conversion factor (a special fraction)
original value: 2.17 m
The converse: original value × conversion factor
*Note that this conversion factor is also useful for converting between feet and meters
original value × conversion factor
kg → lb
___ × ___ = ___
