Notes: Metric SystemMeasurement Activity
It’s a standard system of measurement that allows scientists to compare data and communicate with
other scientists all over the world.
Why use the Systeme International (SI)?
Scientists all over the world use the International System of Units to measure:
• Length• Volume• Mass• Density• Temperature• Time
The basic unit of length in the SI system is the …meter
