Measurement Systems: Metric System Length Meter – distance light travels in 1/299,792,458 th of a second Mass Gram – mass of one cubic centimeter of water Since the gram is such a small unit, the Kilogram (1000 grams) is taken as the base unit Time Second – based on the vibrations of certain atoms, (atomic clocks) Volume Liter or m 3 – based on units of length. 1cm 3 = 1 mL Measurement Systems: Metric System Prefixes are used to represent larger or smaller amounts Each prefix denotes a power of ten.
