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.
Matt and Inez need to determine the correct cage size to obtain in order to safely fit Spout in it. They measure Spout's size in relation to Glowlas and find that eight Glowlas is roughly equivalent to one Spout. When they see Spout on television, they take the opportunity to estimate his size, in meters, by comparing him to a hotel. They choose the cage size based on their estimate.
Beakman and Liza explain meterology and the history of barometers for understanding the weather. Beakman then explains that modern day weather stations are collecting data and combining that with weather satellites to get an idea of what the weather might be. Then he shows how to make a DIY barometer.
