Metric Conversions!Practice Using the Factor-label Method
![Page 2: Practice Using the Factor-label Method. When converting from one unit to another (i.e. kg g, or feet meters), we use Conversion Factors Conversion](https://reader035.vdocuments.us/reader035/viewer/2022081700/56649dab5503460f94a9a343/html5/thumbnails/2.jpg)
When converting from one unit to another (i.e. kg g, or feet meters), we use Conversion Factors
Conversion factors tell us the equivalent magnitude in the new unit◦ For example:
1 in. = 2.54 cm 1 lb = 454 g 1 kg = 2.2 lb
Factor-Label Method for Conversions
![Page 3: Practice Using the Factor-label Method. When converting from one unit to another (i.e. kg g, or feet meters), we use Conversion Factors Conversion](https://reader035.vdocuments.us/reader035/viewer/2022081700/56649dab5503460f94a9a343/html5/thumbnails/3.jpg)
When converting, we make fractions (ratios) out of the conversion factors so that the original unit divides out (cancels out) and the new unit remains:◦ Example:
2.75 pounds is equal to how many kilograms?
Factor-Label Method for Conversions
2.75 lb 1 kg1.25 kg
2.2 lb

1 mile (mi) = 1609 m
1 inch (in) = 2.54 cm
2.2 pounds (lb) = 1 kg
1 lb = 454 g
1 mL = 1 cm3
1 gallon (gal) = 3.785 L
