Converting Kilograms into Grams
To convert kilogram into gram, multiply the number by 1000.
1 kg = 1 × 1000 g = 1000 g
2 kg = 2 × 1000 g = 2000 g
5 kg = 5 × 1000 g = 5000 g
13 kg = 13 × 1000 g = 13000 g
Example : Convert the following into grams :
a. 3 kg b. 5.4 kg c. 0.028 kg
Solution : a. 3 kg = 3 × 1000 g
= 3000 g
b. 5.4 kg = 5.4 × 1000 g
= 5400 g
c. 0.028 = 0.028 × 1000 g
= 28 g
Conversion of Lower Units into Higher Units
To convert millilitre into litre, simply divide the unit by 1000.
Example : Convert the following.
a. 4289 ml into l b. 3608 ml into l and ml
4289
Solution : a. 4289 ml = l = 4.289 l
1000
b. 3608 ml = 3000 ml + 608 ml
3000
= l + 608 ml
1000
= 3 l + 608 ml
= 3 l 608 ml
Conversion of Higher Units into Lower Units
To convert a higher unit into a lower unit, like litre into millilitre, simply multiply the
unit by 1000.
Example : Convert the following.
a. 6 l into ml b. 4 l 540 ml into ml
Solution : a. 6 l = 6 × 1000 ml
= 6000 ml
