1 km -
x 100 ) cm. (10/ 1000)
Answers
For the conversion of standard unit of length the relation between the three units are given below:
1 kilometer = 1000 meters
1 meter = 100 centimeters
Thus,
(i) To convert centimeters (cm) into meters (m), the number of cm is divided by 100.
(ii) To convert kilometer (km) into meters (m), the number of km is multiplied by 1000.
There are other units also for measuring length. A very small length is measured in millimeters (mm).
In between centimeter and meter there is a unit of measuring length named decimeter (dm). It is 10 times of a centimeter.
1 decimeter = 10 centimeters (1 dm = 10 cm)
and, 10 decimeters = 1 meter (10 dm = 1 m)
Now, 10 mm = 1 cm (1 cm = 10 mm)
10 cm = 1 dm (1 dm = 10 cm = 100 mm)
10 dm = 1 m (1 m = 10 dm = 100 cm = 1000 mm)
1 km = 1000 m = 100000 cm
On the basis of these facts, one type of unit is converted into another.
It is the 10th part of a centimeter, i.e., 10 mm = 1cm or 1 cm = 10 mm.
In between centimeter and meter there is a unit of measuring length named decimeter (dm). It is 10 times of a centimeter.
1 decimeter = 10 centimeters (1 dm = 10 cm)
and, 10 decimeters = 1 meter (10 dm = 1 m)
Now, 10 mm = 1 cm (1 cm = 10 mm)
10 cm = 1 dm (1 dm = 10 cm = 100 mm)
10 dm = 1 m (1 m = 10 dm = 100 cm = 1000 mm)
1 km = 1000 m = 100000 cm
On the basis of these facts, one type of unit is converted into another.
