Measurement of something from its one end to the other is called its length. The standard unit of length is meter. We use different units to measure different lengths. Millimeter, centimeter , decimeter are smaller unit used to measure smaller distance, meter is used to measure average distance, whereas units like decameter, hectometer and kilometer are used to measure longer distance. All these units are related to each other.

**Metric Chart**When we move from one metric unit to another to the right in the above metric chart, the value of metric unit becomes ten times smaller i.e. one tenth and when we move from one metric unit to another to the left in the metric chart, the value of metric unit becomes ten times bigger.

__We consider meter as the basic unit of length.__1 Decameter (dam) = 10 times meter

1 Hectometer (hm) = 100 times meter

1 Kilometer (km) = 1000 times meter

1 Decimeter (dm) = 1/10 of meter

1 centimeter (cm) = 1/100 of meter

1 millimeter (mm) = 1/1000 of meter

**Conversion of measures from higher to lower units**We always

__multiply__when we change higher unit to lower unit.__Example 1:__Change 4km into meters1km =1000m

Therefore, 4 x 1000m = 4000m

__Example 2:__Change 25m into centimeters1m = 100cm

Therefore, 25 x 100cm = 2500cm

**Conversion of measures from lower to higher units**We always

__divide__when we change lower unit to higher unit.__Example 1:__Change 6000m to kilometer1000m = 1km

Therefore, 6000 ÷ 1000 = 6km

**Addition and Subtraction**__Step1:__Write the units on the top.__Step2:__Write the numbers in proper place below the units. Write zero in empty place.__Example 1:__Add 45km 34m and 34km 5m__Example 2:__Subtract 15km 30m from 35km 45m**Multiplication involving units of measurement**Example 1: Multiply 23 m 60cm by 5

**Division involving units of measurement**Example 1: Divide 484m 60cm by 4
