1 x 10 = 10 10 X 10 = 100 10 x 100 = 1,000 The Metric System
is based on sets of 10. 1 x 10 = 10 10 X 10 = 100 10 x 100 = 1,000

Is used by scientists all over the world!
The Metric System Is used by scientists all over the world!
4
Do you remember… King Henry?
5
The pneumonic: Memorize this! King Henry Died Unexpectedly
Drinking Chocolate Milk Memorize this!
6
You must also know… …how to convert within the Metric System. Here’s a good device: On your paper draw a line and add 7 tick marks:
7
Next: Above the tick marks write the abbreviations for the King Henry pneumonic: k h dk u d c m m l g s Write the base units in the middle under the “U”.
8
Let’s add the meter line:
k h dk u d c m km hm dkm m dm cm mm
9
Let’s add the liter line:
k h dk u d c m km hm dkm m dm cm mm kL hL dL L dL cL mL
10
Let’s add the gram line:
k h dk u d c m km hm dkm m dm cm mm kl hl dkl l dl cl ml kg hg dkg g dg cg mg
11
Let’s add the second line:
k h dk u d c m km hm dkm m dm cm mm kl hl dkl l dl cl ml kg hg dkg g dg cg mg ks hs dks s ds cs ms

How to use this device: Look at the problem. Look at the unit
that has a number. On the device put your pencil on that unit. Move to new unit, counting jumps and noticing the direction of the jump. 3. Move decimal in original number the same # of spaces and in the same direction.
13
Example #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
14
Example #1: Move to new unit, counting jumps and
noticing the direction of the jump! k h dk u d c m km hm dkm m dm cm mm One jump to the right!
15
Example #1: Move decimal in original number the same # of spaces and in the same direction. 56 cm = _____ mm 56.0. One jump to the right! Move decimal one jump to the right. Add a zero as a placeholder.
16
Example #1: 56 cm = _____ mm 56cm = 560 mm
17
Example #2: Look at the problem. 7.25 L = ____ kL
Look at the unit that has a number L On the device put your pencil on that unit. k h dk u d c m kl hl dkl L dl cl ml
18
Example #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!
19
.007.25 Example #2: Move decimal to the left three jumps.
(3) Move decimal in original number the same # of spaces and in the same direction. 7.25 L = ____ kL Three jumps to the left! Move decimal to the left three jumps. Add two zeros as placeholders.
20
Example #2: 7.25 L = ____ kL 7.25 L = kL
21
Example #3: Try this problem on your own: 45,000 g = ____mg
k h dk u d c m kg hg dkg g dg cg mg
22
45,000.000. Example #3: Three jumps to the right! k h dk u d c m
kg hg dkg g dg cg mg Three jumps to the right! 45,
23
Example #3: 45,000 g = 45,000,000 mg Three jumps to the right!
24
Example #4: Try this problem on your own: 5 cm = ____ km
k h dk u d c m km hm dkm m dm cm mm
25
.00005. Example #4: Five jumps to the left! k h d u d c m
km hm dam m dm cm mm Five jumps to the left!
26
Example #4: 5 cm = km Five jumps to the left!
27
Solve these five problems on your own.
Examples #5-9: Solve these five problems on your own. (5) 35 mm = ____ cm (6) 14,443 L = ____ kL (7) kg = ____ g (8)35.4 L = ____ mL (9)16 mm = ____ km
28
One last caution: Be careful NOT
to count the spot you start from, where you put your pencil point. Only count the jumps!
