How to do Metric Conversions
Metric System
•System of measurement.

•Designed to be easy to
use and universal. (built
on powers of ten)

•Correct name is the
“International System of
Units”( or SI for short).
Built on a Root
 Each property of matter
has a root word that is
the base measurement
for that property.

 For example:
 Grams (g) are for mass
 Liters (L) are for volume
 Meters (m) are for
distance
 To change the value of the root (make it bigger or smaller),

 Smaller
 Milli (m) – 1/1000 of the root (1000 times smaller)
 Centi (c) – 1/100 of the root (100 times smaller)
 Deci (d) – 1/10 of the root (10 times smaller)

 Bigger
 Deka (dk) – 10 times bigger than root
 Hecto (h) – 100 times bigger than root
 Kilo (k) – 1000 times bigger than root.
Easy Conversions
•You can use this simple
kilo-                                                     drawing to convert any
metric measurement to
hecto-                                            another metric
deka-
measurement.
•The stairs have 7 steps

How does it work?
•First, identify the prefixes
kilo-                                                     you are being asked to
convert between.
hecto-
•Example: “Convert
deka-                                        2.345 cm into
hectometers”
root                                 •cm is centimeters and
change is to
deci-                         hectometers.
centi-

How does it Work?
•Next draw out the
kilo-                                                     stairs.
hecto-                                            •Third, put a mark on
the starting prefix (centi

converting to (hecto
deka-            1                       in our example)
root                             •Count the number of
deci-
steps you traveled
and note direction as
centi-
either left or right.
milli-
How Does it Work
 Now go to the original number (2.345) and
move the decimal point the same direction
and number of “steps” as you did on the
stairs.
Fill in empty spaces                    Add new prefix
with zeroes

Practice
 Convert 4.3 km to meters
 Convert 462 cg to hg
 Convert 1 mL to kL
