Count Up to Six and Know Your Left
From Your Right

2. What are Metric Conversions?
Sometimes we need to change from one
measurement to another.
This is usually done because the unit that is
used is either too big or too small for that
type of measurement.

3. TOO BIG !!!
525,568
millimeters
Sometimes the number is too big for the unit
being measured.

4. Too Small
.00654 km
Sometimes the number is too
small for the unit being
measured

5. How Do We Fix This Problem?
We can correct these problems by doing a
process called Metric Conversion. When
you do a Metric Conversion, you are
changing from one unit of measurement to
another.

6. So How Do I Do A Metric
Conversion?
We will be using a method called The Stair-
step Method of Metric Conversion.
It requires two things; one, that you be able to
count to 6, and two, that you know your left
from your right.

7. The Stair-step
Kilo-
Hecto-
Deka-
base units
Deci-
Centi-
Milli-
Grams,
liters,meters

8. The Stair-step

9. You use this chart to convert metric
measurements like this:
If you are measuring length use meter.
If you are measuring dry weight use grams.
If you are measuring liquid capacity use
liter

10. For every step upward on the chart you are
dividing by 10 or moving the decimal one
place to the left..
Example:
To convert 1000 milligrams to grams you are
moving upward on the stairs:
Pretend you are standing on the milli-gram stair
tread and to get to the 1-gram stair tread you move
up 3 steps dividing by 10 each time.

11. Some things to Remember when
converting any type of measures:
To convert from a larger to smaller metric
unit you always multiply
To convert from a smaller to larger unit you
always divide

12. The Latin prefixes used in the metric
system literally mean the number they
represent.
Example:
1 kilogram = 1000 grams
A kilo is 1000 of something just like a
dozen is 12 of something.
This is the metric conversion stair chart.

13. CHECK YOURSELF
Problems:
1.) 3 meters = ______ centimeters
2.) 40 liters = ______ dekaliters
3.) 600 milligrams = _______ grams
4.) 5 kilometers = __________ hectometers
5.) 70 centimeters = _________ meters
6.) 900 deciliters= _______ dekaliters

14. CHECK YOURSELF
7.) John's pet python measured 600
centimeters long. How many meters long
was the snake?
8.) Faith weighed 5 kilograms at birth. How
many grams did she weigh?
9.) Jessica drank 4 liters of tea today. How
many deciliters did she drink?

15. Hey! This Is Easy!
You bet it’s easy! Like we said on the first
slide…..
Be able to count up to six and know your left
from your right.
