2 The Metric SystemThe metric system is a universal measurement system based on the number 10.
3 The main categories of measurement are: Meter (m)—a distance valueLiter (L)—a volume valueGram(g) —a mass valueSecond (s)—a time value
4 Using 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
5 How 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.

7 Example 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
8 Convert 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
