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???

5

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 . 15000

8 MEASURE OF LENGTH Millimeter (mm) 0.1 cm 0.001 m 0.000001 km
Centimeter (cm) 10 mm 0.01 m km Decimeter 100 mm 0.1 m Km Meter (m) 1000 mm 100 cm 0.001 km Dekameter (dam) mm 10 m 0.01 km Hectometer (hm) mm 100 m 0.1 km Kilometer (km) 1,000,000 mm 1000 m

9 YOUR TURN Convert the following measurements.
7 m to mm km to cm   4 km to mm 834 m to km cm to m mm to m cm to km cm to mm m to cm 6.45 m to mm km to mm
