2. History of Measurements

3. The Metrics system provides units for measuring quantities such as length, mass, and volume.
The metric system is based on powers of 10.

4. SI Base Units include Length Meters m Volume Liters L Mass Kilogram kg
Time Seconds s
Electric Current Amperes A
Temperature Kelvin K

5. Derived Units All other units are derived from the base units.
Speed is length / time = meters/seconds
Force is the Newtons.
Force = mass x acceleration = kilograms x meters / seconds2
1Newton =
kilograms x meters/ seconds2

6. The United States uses the English system.
Force in the English system is measured in pounds.
