THE METRIC SYSTEM

## 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

### 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

GOOD LUCK!!
