Converting Between Metric Units
123 cm = __?__ DmTo convert centimeters to Dekameters
Need to move 3 spaces to the leftOne decimal place left makes it 12.3Two decimal places left makes it 1.23
And three decimal places left makes it .123So, 123 cm = .123 Dm

Converting Between Metric Units
.456 Kl = __?__ DlTo convert Kiloliters to Dekaliters
Need to move 2 spaces to the rightOne decimal place right makes it 4.56
And two decimal places right makes it 45.6So, .456 Kl = 45.6 Dl

Converting Between Metric Units
.789 Kg = __?__ mgTo convert from Kilograms to milligrams
Need to move 6 spaces to the rightAfter moving 3 decimal places right you get 789
but are out of numbersSo, you have to add three more zeroes to move
the last three decimal places rightSo, .789 Kg = 789,000 mg

Converting Between Metric Units
24.6 cm = __?__ HmTo convert from centimeters to Hectometers
Need to move 4 spaces to the leftAfter moving 2 decimal places left you get .246 but
are out of numbersSo, you have to add two more zeroes to move the
last two decimal places leftSo, 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 !!!!
