6. 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

10. Here’s the gist of it……. KILO- HECTO- DEKA- UNIT Deci- Centi- Milli-
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

21. Metric Recipe 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, 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.

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

23. 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

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

25. 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.

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

27. 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 dal L dl cl ml

28. 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!

29. .007.25 Move decimal to the left three jumps.
Example #2:
(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.

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

31. Examples #3-7: (3) 35 mm = ____ cm (4) 14,443 L = ____ kL
(5) kg = ____ g
(6)35.4 L = ____ mL
(7)16 mm = ____ km

How many minutes in 7 days?

34. Seconds, Minutes, Hours, Days, Weeks, Months, Years
1 minute = 60 seconds
1 hour = 60 minutes
1 day = 24 hours
1 week = 7 days
1 year = 12 months/ 52 weeks/365 days

35. Warning
This involves Multiplying more than one fraction! The big idea=cancel out your label!

36. Steps Make a plan of the conversions you will need
Example: day-hour-min-sec
First number/fraction is the number they give you
Place label you want to cancel in OPPOSITE location

37. Let’s try together………….
1. How many seconds are there in a day?
1 day 1 ∙ 24ℎ𝑜𝑢𝑟𝑠 1 𝑑𝑎𝑦 ∙ 60 𝑚𝑖𝑛 1 ℎ𝑜𝑢𝑟 ∙ 6𝑜 𝑠𝑒𝑐 1 𝑚𝑖𝑛 = 24∙60∙60 1 = 86,400 sec/day
2. How many minutes are in 10 days?
10 day 1 ∙ 24ℎ𝑜𝑢𝑟𝑠 1 𝑑𝑎𝑦 ∙ 60 𝑚𝑖𝑛 1 ℎ𝑜𝑢𝑟 = 10∙24∙60 1 = 14,400 min in 10 days
3.How many hours are in 64,800 sec?
64,800 𝑠𝑒𝑐 1 ∙ 1 𝑚𝑖𝑛 60𝑠𝑒𝑐 ∙ 1 ℎ𝑜𝑢𝑟 60 𝑚𝑖𝑛 = ∙60 = 64, = 18 hours

38. You try 4. How many minutes in 7 days?
Answer: 10,080 min
5. How many weeks in 20,160 minutes?
