MEASUREMENT OF LENGTH
1. The standard unit to measure length is meters (m).
2. To measure long distances like the distance between Mumbai and Delhi and Chennai, we
use kilometers (km).
3. To measure smaller lengths like length of a room, we use meters (m).
4. To measure even smaller lengths like length of pencil, we use centimeters (cm).
5. We use ruler or tape to measure the length.
6. 100 cms = 1 m
7. 1 cm = 10 millimeter (mm)
8. 1000 m = 1 km
9. To convert meters to centimeters, multiply by 100.
10. To convert kilometers to meters, multiply by 1000.
PRACTICE:
1. Convert 3 meters into centimeters.
2. Convert 5 meters 50 centimeters into centimeters.
3. Convert 12 meters into centimeters.
4. Convert 15 meters and 500 meters into centimeters.
5. Convert 5 kms into meters.
6. Convert 7 kms and 150 meters into meters.
7. Convert 8000 meters into cms.
8. Convert 5000 meters into cms.
9. Form the largest four digit number using the digits 5, 3, 2, 4 only once.
10. Arrange the number with the help of expanded form 1000 + 9 + 20 + 41 + 80 =
1
