# METRIC UNITS OF LENGTH REVIEW

Metric Units of Length Conversions :

1 cm = 10 mm

1 m = 100 cm

1 km = 1000 m

To convert smaller unit into bigger unit, we have to divide.

To convert bigger unit into smaller unit, we have to multiply.

Problem 1 :

12.7 cm = ___ mm

Solution:

Here, we convert bigger unit into smaller unit. So, we have to multiply.

10 mm = 1 cm

12.7 cm = 12.7 × 10 mm

= 127 mm

Problem 2 :

54.54 mm = ___ cm

Solution:

Here, we convert smaller unit into bigger unit. So, we have to divide.

54.54 mm = 54.54/10

= 5.454 cm

Problem 3 :

710 mm = ___ cm

Solution:

Here, we convert smaller unit into bigger unit. So, we have to divide.

1 cm = 10 mm

710 mm = 710/10

= 71 cm

Problem 4 :

94.2 cm = ___ mm

Solution:

Here, we convert bigger unit into smaller unit. So, we have to multiply.

94.2 cm = 94.2 × 10 mm

= 942 mm

Problem 5 :

47.68 cm = ___ mm

Solution:

Here, we convert bigger unit into smaller unit. So, we have to multiply.

47.68 cm = 47.68 × 10 mm

= 476.8 mm

Problem 6 :

653.6 mm = ___ cm

Solution:

Here, we convert smaller unit into bigger unit. So, we have to divide.

653.6 mm = 653.6/10

= 65.36 cm

Problem 7 :

5900 cm = ___ m

Solution:

Here, we convert smaller unit into bigger unit. So, we have to divide.

1 m = 100 cm

5900 cm = 5900/100

= 59 m

Problem 8 :

1450 cm = ___ m

Solution:

Here, we convert smaller unit into bigger unit. So, we have to divide.

1 cm = 100 m

1450 cm = 1450/100

= 14.5 m

Problem 9 :

64.71 m = ___ cm

Solution:

Here, we convert bigger unit into smaller unit. So, we have to multiply.

1 m = 100 cm

64.71 m = 64.71 × 100 cm

= 6471 cm

Problem 10 :

36.32 m = ___ cm

Solution:

Here, we convert bigger unit into smaller unit. So, we have to multiply.

1 m = 100 cm

36.32 m = 36.32 × 100 cm

= 3632 cm

Problem 11 :

7630 cm = ___ m

Solution:

Here, we convert smaller unit into bigger unit. So, we have to divide.

1 m = 100 cm

7630 cm = 7630/100

= 76.3 m

Problem 12 :

25.4 m = ___ cm

Solution:

Here, we convert bigger unit into smaller unit. So, we have to multiply.

1 m = 100 cm

25.4 m = 25.4 × 100 cm

= 2540 cm

Convert between kilometers (km) and meters (m).

Problem 13 :

21 km = ___ m

Solution:

Here, we convert bigger unit into smaller unit. So, we have to multiply.

1 km = 1000 m

21 km = 21 × 1000

= 21000 m

Problem 14 :

19781 m = ___ km

Solution:

Here, we convert smaller unit into bigger unit. So, we have to divide.

1 km = 1000 m

19781 m = 19781/1000

= 19.781 km

Problem 15 :

69580 m = ___ km

Solution:

Here, we convert smaller unit into bigger unit. So, we have to divide.

1 km = 1000 m

69580 m = 69580/1000

= 69.58 km

Problem 16 :

78.32 km = ___ m

Solution:

Here, we convert bigger unit into smaller unit. So, we have to multiply.

1 km = 1000 m

78.32 km = 78.32 × 1000

= 78320 m

Problem 17 :

9.5 km = ___ m

Solution:

Here, we convert bigger unit into smaller unit. So, we have to multiply.

1 km = 1000 m

9.5 km = 9.5 × 1000

= 9500 m

Problem 18 :

41300 m = ___ km

Solution:

Here, we convert smaller unit into bigger unit. So, we have to divide.

41300 m = 41300/1000

= 41.3 km
