We can measure the length of something. We can measure in inches, feet, and yards! We can even measure a mile!
We can measure the weight of things. How heavy is it? How light is it?
We can measure the size of liquids. How many cups is it? How many pints is it? How many quarts is it? How many gallons is it?
We can measure how big or small, long or short, heavy or light things are. We can measure how much space they take up!
In the United States we measure using the U.S. Standard measurement system. Inches, feet, ounces and pounds, and cups, pints, quarts and gallons are units we use to measure with U.S. Standard.
Many countries use the Metric system to measure. Meters and centimeters, kilos and kilograms, and liters and milliliters are units of measurement in the Metric System.
