Project Summary: Conversions In Unit 7, you are learning about the metric system and making conversions within the metric system. Many believe that conversions within the metric system are easier to make, while others believe conversions within the U.S. system are easier. During this unit, you will explore two different measurement systems: The metric system and the U.S. system of measurement. You will be exposed to both measurement systems either by converting a measurement in that specific system or commenting on a student’s conversion in a different system.
