### Converting Between Metric Units

K H DByd c m

123 cm = __?__ Dm

To convert centimeters to Dekameters

Need to move 3 spaces to the left

One decimal place left makes it 12.3

Two decimal places left makes it 1.23

And three decimal places left makes it .123

So, 123 cm = .123 Dm

### Converting Between Metric Units

K H DByd c m

.456 Kl = __?__ Dl

To convert Kiloliters to Dekaliters

Need to move 2 spaces to the right

One decimal place right makes it 4.56

And two decimal places right makes it 45.6

So, .456 Kl = 45.6 Dl

### Converting Between Metric Units

K H DByd c m

.789 Kg = __?__ mg

To convert from Kilograms to milligrams

Need to move 6 spaces to the right

After moving 3 decimal places right you get 789 but are out of numbers

So, you have to add three more zeroes to move the last three decimal places right

So, .789 Kg = 789,000 mg

### Converting Between Metric Units

K H DByd c m

24.6 cm = __?__ Hm

To convert from centimeters to Hectometers

Need to move 4 spaces to the left

After moving 2 decimal places left you get .246 but are out of numbers

So, you have to add two more zeroes to move the last two decimal places left

So, 24.6 cm = .00246 Hm

### Remember . . .

A meter is . . .

about the height of a tennis net.

A centimeter is . . .

about the width of a paperclip.

A kilometer is . . .

about 5 city blocks.

### Remember . . .

A mililiter is about. . .

a medicine dropper full.

A liter is . . .

about a bottle of pop.

Kiloliters would be . . .

how you would measure the water in a pool.

### And Remember . . .

A milligram is . . .

about the mass of a grain of salt.

A gram is . . .

about the mass of a paperclip.

A kilogram is . . .

about the mass of a baseball.

Good Luck !!!!
