Everyday Examples of Metric

The easiest way to start to think of metric is to know some physical examples of metric units as benchmarks. Rather than converting from feet, pounds, or gallons, learn some examples of metres, kilograms, and litres.

The following table has some approximate examples of metric measurements:
