5. Metric Conversions Ladder Method
T. Trimpe

6. How many jumps does it take?
Ladder Method 1 2 3
KILO 1000 Units
HECTO 100 Units
DEKA 10 Units
DECI 0.1 Unit
Meters Liters Grams
CENTI 0.01 Unit
MILLI Unit
How do you use the “ladder” method?
1st – Determine your starting point.
2nd – Count the “jumps” to your ending point.
3rd – Move the decimal the same number of jumps in the same direction.
4 km = _________ m
Starting Point
Ending Point
How many jumps does it take? 4. 1
__. 2
__. 3
__.
= 4000 m

7. BASIC UNITS (page 29)
OF THE METRIC SYSTEM

9. Converting Units
To convert from one unit to another is like following directions on a map.
Which way?
Left or Right?

10. Going Left???
When going from a smaller unit to a
larger unit, you move Left on the
map and the decimal moves to the
LEFT .

11. Going Right???
When going from a larger unit to a smaller unit, you move RIGHT on the map and the decimal moves to the RIGHT .

12. Practice Time
4.5 m = ? cm

13. . . . 4.5 What to do first in the problem 4.5 m = __ cm ?
Start at Meters and move to the Right to Centimeters.
Decimal place moves to the RIGHT two spaces. . . .
Kilo
Hecto
Deka
Basic Unit
Deci
Centi
Milli
4.5

14. As you move the decimal
you will need to add zeros. .

15. Is this your Final Answer?
4.5 m = 450 cm

16. Let’s do another one!
6.6 liters = _____ mL

17. . . . . 6.6 What to do first in the problem 6.6 L = __ mL ?
Start at Liters and move to the Right to Millileters.
Decimal place moves to the RIGHT three spaces. . . . .
Kilo
Hecto
Deka
Basic Unit
Deci
Centi
Milli
6.6

18. Check your answer!
6.6 liters = 6,600 mL

19. Let’s Go the Other Way!
3,580 mm = _______ m?

20. . . . . 3 5 8 0 Let’s move to the left this time.
3,580mm = ___________m?
Start at Millimeters and move to the Left to Meters.
Decimal place moves to the LEFT three spaces. . . . .
Kilo
Hecto
Deka
Basic Unit
Deci
Centi
Milli

21. Check your answer:
3,580mm = 3.58m

22. Quiz Time
28 cm = ? mm
438 cm = ? m
72 g = ? mg
202 g = ? Kg
2L = ? mL

23. How did We do??
cm =
280 mm
cm =
4.38 m
g =
72,000 mg
g =
0.202 kg
5. 2 L =
2,000 mL

24. Now we will practice with the following worksheets
Units of length
Metric conversion

25. Conversion Practice Try these conversions using the ladder method.
1000 mg = _______ g 1 L = _______ mL 160 cm = _______ mm
14 km = _______ m 109 g = _______ kg 250 m = _______ km
Compare using <, >, or =.
56 cm m 7 g mg

26. Compare using <, >, or =.
25) 63 cm m 27) 5 g mg 29) 1,500 mL L
26) 536 cm dm 28) 43 mg g 30) 3.6 m cm

27. Metric Conversion Challenge
