THE METRIC SYSTEM

is based on sets of 10

1 x 10 = 1010 X 10 = 100

10 x 100 = 1,000

Is used by scientists all over

the world!

To convert from a smaller unit to a larger unit

(going to the left) divide by 10 for each step.

(Move the decimal one time to the left for each box)

Ex: 4 millimeters= 0.4 centimeters

To convert from a larger unit to a smaller unit (going to the right ) multiply by 10 for each box (Move the decimal one time to the right for each step.

Ex: 25 kilograms = 25000 grams

METRIC RECIPE

1. Look at the problem. Look at the unit

that has a number. On the device put

your pencil on that unit.

2. Move to new unit, circle it counting jumps and noticing the direction of the jump.

3. Move decimal in original number the same # of spaces and in the same direction.

ONE LAST CAUTION:

Be careful NOT

to count the spot you start from, where you put your pencil point.

Only count the jumps!

EXAMPLE #1:(1) Look at the problem. 56 cm = _____

mm

Look at the unit that has a number. 56 cm

On the device put your pencil on that unit. k h d U d c m

km hm dam m dm cm mm

EXAMPLE #1:

k h d U d c m

km hm dam m dm cm mm

2. Move to new unit, counting jumps and noticing the direction of the jump!

One jump to the right!

EXAMPLE #1:

3. Move decimal in original number the same # of spaces and in the same direction.

56 cm = _____ mm

56.0.

Move decimal one jump to the right. Add a zero as a placeholder.

One jump to the right!

EXAMPLE #1:

56 cm = _____ mm

56cm = 560 mm

EXAMPLE #2:

(1) Look at the problem. 7.25 L = ____ kL

Look at the unit that has a number. 7.25 L

On the device put your pencil on that unit.

k h d U d c m

kl hl dal L dl cl ml

EXAMPLE #2:

2. Move to new unit, counting jumps and

noticing the direction of the jump! k h d U d c m

kl hl dal L dl cl ml

Three jumps to the left!

EXAMPLE #2:

(3) Move decimal in original number the same # of spaces and in the

same direction. 7.25 L = ____ kL

.007.25Move decimal to the left three jumps. Add two zeros as placeholders.

Three jumps to the left!

EXAMPLE #2:

7.25 L = ____ kL

7.25 L = .00725 kL

EXAMPLES #3-7:

(3) 35 mm = ____ cm

(4) 14,443 L = ____ kL

(5) 0.00056 kg = ____ g

(6)35.4 L = ____ mL

(7)16 mm = ____ km
