Why Metric Is Easier

How many inches are in 2.5 miles? You need 1760, 3 and 12 to work it out. How many millimeters are in 2.5 kilometers? Just move the decimal point. This video shows why metric units are so much easier: every prefix is a power of ten, so converting between them never needs awkward multiplication. It covers the US customary (imperial) chains for length and weight, the kilo, milli and mega prefixes, and how to move the decimal point in the right direction.
