2. 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

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 d u d c m m l g
Write the units in the middle under the “U”.

8. Let’s add the meter line:
k h d u d c m
km hm dkm m dm cm mm l g

9. Let’s add the liter line:
k h d u d c m
km hm dkm m dm cm mm
kl hl dkl l dl cl ml g

10. Let’s add the gram line:
k h d 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. 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.

12. 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 dkm m dm cm mm

13. Example #1: Move to new unit, counting jumps and
noticing the direction of the jump!
k h d u d c m
km hm dkm m dm cm mm
One jump to the right!

14. 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.

15. Example #1:
56 cm = _____ mm
56cm = 560 mm

16. 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 d u d c m
kl hl dkl L dl cl ml

17. Example #2: Move to new unit, counting jumps and
noticing the direction of the jump!
k h d u d c m
kl hl dkl L dl cl ml
Three jumps to the left!

18. .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.

19. Example #2:
7.25 L = ____ kL
7.25 L = kL

20. Example #3: Try this problem on your own: 45,000 g = ____mg
k h d u d c m
kg hg dkg g dg cg mg

21. 45,000.000. Example #3: Three jumps to the right! k h d u d c m
kg hg dkg g dg cg mg
Three jumps to the right!
45,

22. Example #3:
45,000 g = 45,000,000 mg
Three jumps to the right!

23. Example #4: Try this problem on your own: 5 cm = ____ km k h d u d c m
km hm dkm m dm cm mm

24. .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!

25. Example #4:
5 cm = km
Five jumps to the left!

26. Examples #5-9: (5) 35 mm = ____ cm (6) 14,443 L = ____ kL
(7) kg = ____ g
(8)35.4 L = ____ mL
(9)16 mm = ____ km

27. One last caution: Be careful NOT
to count the spot you start from, where you put your pencil point.
Only count
the jumps!
