Example 2: Convert the following.
(a) 0.4325 km into m (b) 7.24 dam into cm

Solution: (a) 0.4325 km = 0.4325 × 1000 m
× 10 × 10 × 10
= 0432.5000 m

= 432.5 m km hm dam m
(b) 7.24 dam = 7.24 × 1000 cm
× 10 × 10 × 10
= 7240.00 cm

= 7240 cm dam m dm cm
Conversion of Weight

Example 3: Convert the following.
(a) 37 kg into g (b) 40 dag into cg (c) 153 hg into g (d) 305 dg into cg

Solution: (a) 37 kg into g × 10 × 10 × 10
37 kg = 37 × 1000 g kg hg dag g

= 37000 g
(b) 40 dag into cg × 10 × 10 × 10

40 dag = 40 × 1000 cg dag g dg cg
= 40000 cg
(c) 153 hg into g × 10 × 10

153 hg = 153 × 100 g hg dag g
= 15300 g

(d) 305 dg into cg × 10
305 dg = 305 × 10 cg = 3050 cg dg cg
Example 4: Convert the following.

(a) 432.8 hg into mg (b) 803.75 dag into cg
Solution:

(a) 432.8 hg into mg × 10 × 10 × 10 × 10 × 10
432.8 hg = 432.8 × 100000 mg
hg dag g dg cg mg
= 43280000 mg

(b) 803.75 dag into cg × 10 × 10 × 10
803.75 dag = 803.75 × 1000 cg = 803750 cg dag g dg cg

Get it right!
7.25 m = (7.25 × 100) m 7.25 m = (7.25 × 100) cm

= 725 m = 725 cm
