### The Metric System

The metric system is a universal measurement system based on the number 10.

The main categories of measurement are:
• Meter (m)—a distance value
• Liter (L)—a volume value
• Gram(g) —a mass value
• Second (s)—a time value
To the left to raise the values

To the right to lower the values

Using the above values as the base, they can be subdivided by moving the decimal point
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.

Right

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 right
• Correct answer is 20,000 m
Convert the following values by moving the decimal point the correct number of spaces and in the right direction:
• 23.5 m = cm
• 134.56 mm =m
• 98.43 L = mL
• 34 g = Kg
• 123.4 cg = Hg
• 456.3 g = cg
• 3908 Kl = mL
• .045 mg = cg
• 2.0 m = mm
• 20 km = m
