Transcript INTERNATIONAL SYSTEM UNITS
There are seven base units in the system, from which
other units are derived.
The metric system is the most widely used system of measurement in the
world. It is a more universal measurement standard as compared to the
customary system used in the United States.
The three basic units of the metric system are the meter, gram, and liter:
The gram measures weight.
The meter measures length.
The liter measures capacity.
The purpose of a metric is to get rid of the ambiguity between, for
example inches, feet and yards. It is difficult to transfer back and
forth between these different units of measure, so a single unit
(the "metric" of the system) is set, and every other unit is based on
a clear, easy to translate multiple. Since we use 10 as our base, it is
only natural to do the same with units of measure. This way
transitioning between different units requires only moving the
decimal place.

THEN… MEASURE THE FOLLOWING ELEMENTS.
1. A Pen is ______cm
2. A glue stick is ________ cm
3. You are ________m tall

Centimeter (cm)
10 mm
0.01 m
0.00001 km
Decimeter
100 mm
0.1 m
0.0001 Km
Meter (m)
1000 mm
100 cm
0.001 km
Dekameter (dam)
10.000 mm
10 m
0.01 km
Hectometer (hm)
100.000 mm

1000 m
FOLLOW THESE SHORT 3 STEPS:
1. Count the number of zeros in the number you are
multiplying or dividing by.
2. If you are multiplying, move the decimal point
this number of places to the right.
7m to mm =
7x 1000=
7.000 mm
All the measurements can either be multiplied or
divided by 10, 100, 1,000, and so on.
3. If you are dividing, move the decimal point this
number of place to the left.
836 m to Km = 836 / 1000
0.834 mm
Convert the following measurements.
• 7 m to mm
• 834 m to km
•
730 000 cm to km
•
6.45 m to mm
5 km to
cm
5 cm to m
8.34 cm to mm
3.05 km to mm
4 km to mm
4000 mm to m
8.2 m to
cm
