Examples on Mass :-
1) Convert 1250 milligram (mg) to gram. Solution: milligram is the smaller unit than gram.
So, S(small)→B (Big) → ÷
∴ 1250 mg = 1250 / 1000 = 1.250 g.

2) Convert 52 kg to gram. Solution: kg is the bigger unit than gram.
So, B(Big)→ S (Small) → X
∴ 52 kg = 52 x 1000 = 52,000 g.

3) Convert 1.2 hectogram to gram. Solution: hg is the bigger unit than gram.
So, B(Big)→ S (Small) → X
∴ 1.2 hg = 1.2 x 100 = 120 g.

4)A new born baby is 3835 g. How many kg is that? Solution : gram is the smaller unit than kg.
So, S(small)→B (Big) → ÷
∴ 3835 g = 3835 / 1000 = 3.835 kg.

5) An empty suitcase is 2.50 kg. How many decagram is that ? Solution : Here the weight of suitcase is in kg which bigger unit than decagram.
∴ Apply B(Big)→S (Small) → X
⇒ 2.50 kg = 2.50 x 100 = 250 decagram.

6) Mr. Ryan bought 500 g apples, 750 g grapes and 250 g strawberries, and 1 kg oranges. How many kg of fruit did she buy? Solution :
1 kg oranges = 1000 g oranges
Total fruits = Apples + grapes + strawberries + oranges
= 500 + 750 + 250 + 1000
= 2500 g
gram is a smaller unit than kg
So S(small)→B (Big) → ÷
∴ 2500 g = 2500 /1000
= 2.5 kg Measurements Length Weight Capacity
