METRIC SYSTEM

In the late 1700’s, the French Academy of Sciences developed the Metric System.

The system is now the International System of Units (SI).

Si units are expressed in multiples of 10.

BASIC UNITS

The basic units are: meter, liter and gram.

Meter is the basic unit of length.

Liter is the basic unit of volume.

Gram is the basic unit of mass.

STEPS

Smaller unit to a bigger unit you divide.

Bigger unit to a smaller unit you multiply.

CONVERSIONS

1000 m = 1 km

1000 km = 1000000 m

1000 cm = 10 m

1000 m = 100000 cm

1000 mm = 1 m

1000 g = 1 kg

1000 kg = 1000000 g

1000 cg = 10 g

1000 g = 100000 cg

1000 mg = 1 g

1000 l = 1 kl

1000 kl = 1000000 l

1000 cl = 10 l

1000 l = 100000 cl

1000 ml = 1 l

METER

1. 2 m to cm = 200 cm

2. 2 cm to m = 0.02 m

3. 2 km to m = 2000 m

4. 2 mm to cm = 0.2 cm

5. 2 mm to km = 0.000002 km

GRAM

1. 2 g to kg = 0.002 kg

2. 2 kg to g = 2000 g

3. 2 mg to g = 0.002 g

4. 2 g to kg = 0.002 kg

5. 2 cg to g = 0.02 g

LITER

1. 5 ml to l = 0.005 l

2. 10 ml to l = 0.01 l

3. 10 l to ml = 1000 ml

4. 525 l to ml = 525000 ml

5. 24 cl to l = 0.24 l
