The metric system has the advantage of being a completely decimal system. The units of measure in the metric system relate to one another by multiples of ten. This makes the metric system mathematically logical and easy to use. Instead of working with complicated division and multiplication to change from one measurement unit to another, the decimal point is merely moved. For example, to change 357 centimeters to meters, divide by 100.
Metric measures make calibration of instruments and equipment much easier.
Compare U.S. standard measure and metric measure tools and identify engines and machinery which require metric measure tools. To convert units, mulitply unit on left by conversion factor on right.
