(b) 5002 mg = 5000 mg + 2 mg

= (5000 ÷ 1000) g + 2 mg Think and Answer
= 5 g 2 mg Which is heavier: a
stone of 1 kg or a sack
Other units of Measuring Weight of 1 kg cotton?

Quintal and ton are other two units used for measuring heavy weights.

Often, we measure the weight of a sack of wheat and that of rice in quintals.
Heavy things like trucks and containers are measured in tons.

1 Quintal = 100 kg

1 Ton = 10 Quintals = 1000 kg
example 5: Convert the following:

(a) 3 tons into kg (b) 520 kg into quintals
(c) 5 tons into quintals (d) 4 tons 2 quintals into kg

Solution: (a) We have, 1 ton = 1000 kg

Therefore, 3 tons = 3 × 1000 = 3000 kg
(b) We have, 100 kg = 1 quintal

Therefore, to convert kg into quintal, we will divide 100.

520 ÷ 100 gives Q = 5 and R = 20
So, 520 kg = 5 quintals 20 kg 100 520 5 quintal
500
(c) We have, 1 ton = 10 quintals 20 kg
Therefore, 5 tons = 5 × 10 = 50 quintals

(d) We have, 1 ton = 10 quintals = 1000 kg and 1 quintal = 100 kg
Therefore, 4 tons 2 quintal is

= 4 × 1000 kg + 2 × 100 kg Alternative Method
= 4000 kg + 200 kg 4 tons 2 quintals
= (4 × 10 + 2) quintals ( 1 ton = 10 quintals)
= 4200 kg = 42 quintals = 42 × 100 kg ( 1 quintal = 100 kg)
= 4200 kg

Practice time 10c

1. Convert the following.

(a) 26 kg into g (b) 320 kg 45 g into g
(c) 45 g into mg (d) 140 g 203 mg into mg

2. Convert the following into g.

(a) 9 kg 1 hg 4 dag 5 g (b) 20 kg 4 hg 9 dag 8 g
