Hi! Let's explore two different ways we measure things every day.
We use customary units in the United States. We measure length in inches and feet. We measure weight in pounds.
Most other countries use metric units. Meter sticks measure length. Grams and kilograms measure weight.
Leo changed his mind about tools. At first, he used inches. Then, he saw meters were easier for his team project.

- Look at the choices: inches and meters.
- Remember that inches are customary units.
- Remember that meters are metric units.
- Pick meters because Leo wants a metric unit.
