2The Metric SystemThe metric system is a universal measurement system based on the number 10.
3The main categories of measurement are: Meter (m)—a distance valueLiter (L)—a volume valueGram(g) —a mass valueSecond (s)—a time value
4Using the above values as the base, they can be subdivided by moving the decimal point To the left to raise the valuesTo the right to lower the values
5How to move the decimal point: To move from a larger value to a smaller value, move the decimal point to the right.To move from a smaller value to a larger value, move the decimal point to the left.

7Example problem #1: Convert 20.0 km to m. Kilometers are larger than meters.So to move from a larger value to a smaller value, move the decimal point to the right.Count the number of spaces moved on the chart. You would move 3 spaces from kilo to meters (base unit)Then move the decimal point 3 spaces to the rightCorrect answer is 20,000 m
8Convert the following values by moving the decimal point the correct number of spaces and in the right direction:23.5 m = cmmm = m98.43 L = mL34 g = Kg123.4 cg = Hg456.3 g = cg3908 Kl = mL.045 mg = cg2.0 m = mm20 km = m
