1. INTERNATIONAL SYSTEM OF UNITS

2. THE METRIC SYSTEM
The three basic units of the metric system are the GRAM, METER and LITER:
The GRAM measures The METER measures The LITER measures
weight length. capacity.

3. The purpose of a metric is to get rid of the ambiguity between, for example inches, feet and yards. 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.
METRIC MEASURES

4. HOW IS THIS POSSIBLE???

6. Basic unit: METER Kilometer Km Hectometer hm Decameter dam Meter m
Decimeter dm
Centimeter cm
Millimeter mm

7. You have to multiply when yo go down.
LET´S DO IT TOGETHER
Kilometer Km
Hectometer hm
Decameter dam
Meter m
Decimeter dm
Centimeter cm
Millimeter mm
Convert 15 Km to m…
You have to multiply when yo go down.
Add zeroes to the right .
