WEIGHT

Maths (Primary Classes)

The units used for measuring weight are kilogram (kg) and gram (g).

1000 gram = 1kg

1000kg = 1 ton

 

EXAMPLE1

Change to kilogram

2000g to kilogram

 

1000g = 1kg

2000g = m

Cross multiply

1000 × m = 2000 x 1

1000m = 2000

m = 2000 = 2kg

                    1000

Solution

To change from kg to grams, multiply by 1000

5kg = 5 x 1000

= 5000 grams
