Metrics
• You can do this!

2
Units of the metric system
meter - length
gram - mass
liter - capacity
3
Metric Prefixes
kilo hecto deka meter deci centi milli
1,000 100 10 1 0.1 0.01 0.001
Do you see a pattern?
4
The order is very important.
How can we remember all of this?
5
Lets learn a silly saying.
abbreviations in the metric system.

Kiss Hogs Down At Motel - Dont Crush MMs
Write down the abbreviations in order from
greatest to least.
It is easy to do when you remember the silly
saying.
km hm dam m dm cm mm
13
1 m ___ mm
km hm dam m dm cm mm
Start at m (for meter). Millimeter is 3 places
to the right. So all we have to do is move the
decimal 3 places to the right.

I have moved the decimal 3 places to the right.
There are 3 empty spaces so I need to add 3
zeros.
1 m ____ mm
1,000
Moving the decimal 3 places to the right is the
same thing as multiplying by 1000.
15
1 m ___ km
km hm dam m dm cm mm
Start at m (for meter). Kilometer is 3 places to
the left. So all we have to do is move the
decimal 3 places to the left.

I have moved the decimal 3 places to the left.
There are 2 empty spaces so I need to add 2
zeros.
1 m ____ km
0.001
Moving the decimal 3 places to the left is the
same thing as dividing by 1000.
17
Lets do another problem.
18
15 hm ___ cm
km hm dam m dm cm mm
Start at hm (for hectometer). Centimeter is 4
places to the right. So all we have to do is
move the decimal 4 places to the right.

150,000
Moving the decimal 4 places to the right is the
same thing as multiplying by 10,000.
15 X 10,000 150,000

The wonderful thing about the metric system is
that everything is based on 10.If you know how
to convert length in the metric system, then you
also know how to convert mass in the metric
system.
21
In the metric system, the basic unit for
measuring mass is the gram.

gram
22
The same silly saying will help with mass.
(Do you remember the silly saying?)
Kiss Hogs Down At Motel - Dont Crush MMs
km hm dam m dm cm mm
kg hg dag g dg cg mg
The m stands for meter. We will substitute a g
for gram to measure mass.The order doesnt
change at all.
23
1 g ___ mg
kg hg dag g dg cg mg
Start at g (for gram). Milligram is 3 places to
the right. So all we have to do is move the
decimal 3 places to the right.

25
If you know how to convert length (meter) and
mass (gram) in the metric system, then you also
know how to convert capacity (Liter) in the
metric system.
26
In the metric system, the basic unit for
measuring capacity is the liter.
2 liter bottle of pop1 liter bottle of water
27
The same silly saying will help with capacity.
(Do you remember the silly saying?)

kL hL daL L dL cL mL
The m stands for meter. We will substitute a L
for liter to measure capacity.The order doesnt

3.6 kL ___ mL
kL hL daL L dL cL mL
Start at kL (for kiloliter). Milliliter is 6
places to the right. So all we have to do is
move the decimal 6 places to the right.

3,600,000
Moving the decimal 6 places to the right is the
same thing as multiplying by 1,000,000.
3.6 X 1,000,000 3,600,000

In 12 kilograms there are exactly how many
hectograms?
120 hectograms
31
To convert 60 kilometers to meters?
Multiply 60 by 1,000
32
A car traveled 300 kilometers. What is the
distance traveled in meters?
300,000 meters
33
To convert 24 milliliters to liters, the number
of milliliters should be divided by what number?
1,000
