                  We also measure the weight 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 weight (mass).

                  Standard Units of Weight

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

                  Gram
                  The smaller unit of weight (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.
