# Conversion of length

Convert into millimeter, Convert into centimeters, Convert into meter, Convert into kilometer

Conversion

Let us know

To convert upper scale into lower scale the number should be multiplied.

To convert lower scale into upper scale the number should be divided.

100 centimeter = 1 meter

½ meter = 50 centimeter

¼ meter = 25 centimeter

¾ meter = 75 centimeter

1000 meter = 1 kilometer

Activity

Measure the things using a tape or a scale.

Examples 1

Convert into millimeter

(i) 70 cm

70 cm = 70 × 10 mm 1 cm = 10 mm

=700 mm

(ii) 65 cm 6 mm = (65 × 10) + 6 mm

= 650 + 6

= 656 mm

(iii) 7 m

7 m = (7×1000) mm 1 m = 1000 mm

= 7000 mm

Note:

1. To convert meter into millimeter multiply the given meters by 1000.

2. To convert centimeter into millimeter multiply the given centimeter by10.

Try this

Convert into millimeters

1. 90 cm = 900 mm

2. 5 cm 8 mm = 58 mm

3. 5 m 9 mm = 5009 mm

Examples 2

Convert into centimeters

(i) 5 m

5 m = (5 × 100) cm

= 500 cm

(ii) 7 m 40 cm

7 m 40 cm = (7 × 100) + 40 cm

= 700 + 40

= 740 cm

(iii) 110 mm

110 mm = 110 ÷ 10 cm

= 11 cm

Note: To convert meter into centimeter multiply the given meters by 100

Try this

Convert into centimeters

1. 8m = 800 cm

2. 6m 4cm = 604 cm

3. 80mm = 8 cm

Examples 3

Convert into meter

(i) 7 km 50 m

1 km = 1000 m

7 km 50 m = (7 × 1000) + 50 m

= 7000 + 50

= 7050 m

(ii) 850 cm

850 cm = 850 ÷ 100 m

= 8 m 50 cm

(iii) 2005 mm

2005 mm = 2005 ÷ 1000 m

= 2 m 5 mm

Note:

1. To convert kilometer into meter multiply the given kilometer by 1000.

2. To convert millimeter into meter given divide the given millimeter by 1000.

Try this

Convert into meter

1. 8 km 400 m = 8400 m

2. 900 cm = 9 m

3. 3500 mm = 3 m 500 mm

Examples 4

Convert into kilometer

(i) 9000 m

1000 m = 1 km

9000 m = 9000 ÷ 1000 m

= 9 km

(ii) 2300 m

2300 m = 2300 ÷ 1000 m

= 2 km 300 m

Note: To convert meters into kilometers divide the given meters 1000.

Try this: Convert into kilometer

1. 5430m = 5 km 430 m

2. 7500m = 7 km 500 m

3. 8000m = 8 km
