Cintronella Jones catches a man making counterfeit meter sticks and arrests him because he is violating measurement standards. Later, a girl indicates that a meter is standardized across different countries in the world and even on the moon.
Bill provides a brief background on the history of measurement and explains why humans developed standard units of measurement. He explains how the meter was developed and talks about the simplicity of the metric system.
Bill shows how units of length, such as a meter, can be used to measure the mass of an object. He mentions a few unit conversions, most notably that a liter of water is equivalent to a kilogram and stresses that only three-tenths of a meter and water are needed to measure an object's mass.
