              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.
