Many measurements in the United States are made in metric units. A drink may come in bottles, calcium may come in capsules, and we may run a race. To work easily in both systems, we need to be able to convert between the two systems.
[link] shows some of the most common conversions.
| Conversion Factors Between U.S. and Metric Systems | ||
|---|---|---|
| Length | Weight | Volume |
|
in =
cm
ft = m yd = m mi = km m = ft |
lb =
kg
oz = g kg = lb |
qt =
L
fl oz = mL L = qt |
