                  We also measure the mass of one heavier object in terms of other lighter objects
                  using a balance. Look at these pictures and fill in the boxes.

                  (a)                                 (b)                              (c)

                        1 papaya weighs as                 6 books weigh as                  2 dolls weigh as much

                        much as  7  oranges.               much as          school           as       pencil boxes.

                                                           bag.
                  All these objects such as a cup, spoon, pebbles, blocks, etc., used for measurement

                  are called non-standard units of mass (weight).

                  Standard Units of Weight (Mass)

                  To measure the weight of objects accurately we use the standard units of weight.
                  Gram

                  The smaller unit of mass is gram. In short

                  it is written as g. It is used to measure the

                  weight of lighter objects such as an orange,
                  a soap bar, coin, etc.                                   About 150 g       About 100 g       About 4 g

                  Kilogram

                  The standard unit of weight (mass) is

                  kilogram. In short it is written as kg.

                  It is used to measure the weight of heavy
                  objects such as bags of vegetables, boxes

                  of fruits, flour, rice, etc.                           About 1 kg       About 10 kg       About 25 kg

                  You can see the weights of grams and kilograms used for measuring weight while
                  buying vegetables and fruits.

                  If we put 1000 grams together, we get 1 kilogram. So, 1000 g = 1 kg
