METRIC SYSTEM
Definition Of Metric System
Metric System is a base ten system of measurement, where each unit is defined in terms of multiples of 10.
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.
Quick Summary
- The metric system uses base 10 for easy conversions.
- Common units include meters (m), grams (g), and liters (L).
- Prefixes like kilo-, centi-, and milli- indicate multiples or fractions of the base unit.
