1.3 Converting units A conversion factor is a ratio that has the value of one. This method of converting units is called dimensional analysis. To do the conversion you multiply 4.5 feet by a conversion factor.

Convert 4.5 ft to cm Looking for: Given: Relationships: Solution: Solving Problems Convert 4.5 ft to cm Looking for: You are asked for the distance in cm Given: You are given the distance in ft. Relationships: Ex. There are ? cm in 1 ft? 30.48 cm = 1 ft Solution: Make a conversion factor from equivalent

1.3 Converting units Use the correct conversion factor to convert: 175 yds. to m. 2.50 in. to mm.
