More About Metric System
The above figure shows the consecutive metric units of length. This is used in conversion of units of length easily.
10 millimeter (mm) = 1 centimeter (cm)
10 centimeter cm = 1 decimeter (dm)
10 decimeter (dm) = 1 meters (m)
1 dekameter (dam) = 10 meters (m)
hectometer (hm) = 10 dekameter (dam)
kilometer (km) = 10 hectometer (hm)

Examples of Metric System
As the Metric System uses base ten system of measurement, each unit can easily be converted into other and vice-versa.
900 cm can be converted to meter by using relationship 1 m =100 cm.
So, 900 cm = 9 × 100 cm = 9 m.
Solved Example on Metric System
Ques: Tanya traveled a distance of 49.4 km. Convert that distance into meters.
Choices:
A. 4940 m
B. 49.4 m
C. 49400 m
D. 494 m
Correct Answer: C
Solution:
Step 1: 1 km = 1000 m
Step 2: Distance traveled by Tanya = 49.4 km
Step 3: = 49.4 × 1000 m [Convert kilometers into meters.]
Step 4: 49400 m [Simplify.]
Step 5: Distance traveled by Tanya = 49400 m.
