  2. The Metric System • The metric system is a measurement system based on the number10. • Math is easy because calculations are multiples of 10 • Other countries and scientists and engineers use the metric system for measurement. • It is called the “International System” (SI System) • In the United States we use both “Customary Units” based old English measures and metrics

  3. Metric Units • Length… m______ • Mass… g_____ • Volume…l______

  4. Metric Prefixes • Metric Units have prefixes that are multiples of 10. • What do we call a thousand meters? • What do we call one tenth of a liter?

  5. Meters • Meters measure length or distance • One millimeter is about the thickness of a dime.

  6. Meters • One centimeter is about the width of a pinky finger
