    Study Notes

    Metric Units

    • The amount of matter in an object is called mass.
    • The metric system uses kilograms (kg) for mass.
    • 1000 grams (g) = 1 kilogram (kg)
    • 1000 milligrams (mg)= 1 gram(g)
    • 1000 micrometers (µm) = 1 millimeter (mm)

    English Units

    • The English system uses ounces (oz) for mass.
    • 16 ounces (oz) = 1 pound (lb)
    • 1000 grams (g) = 35.3 ounces (oz)
    • 1 kg = 2.2 lbs

    Conversions

    • 1 kilometer (km) = 1000 meters (m)
    • 1 meter (m) = 100 centimeters (cm)
    • 1 centimeter (cm) = 10 millimeters (mm)
    • 1 millimeter(mm) = 1000 micrometers (µm)

    How to Determine the Correct Units

    • Look at the graph's title
    • Look at the axis labels.
