    Kilograms and grams into grams

                To convert kilograms and grams into grams, we multiply the number of kilograms by
                1000 and add the product to the number of grams.

                examples:  a.  3 kg 120 g = (3 × 1000 ) g + 120 g = 3000 g + 120 g = 3120 g
                               b.  9 kg 378 g = (9 × 1000 ) g + 378 g = 9000 g + 378 g = 9378 g

                Making equal Weights

                    Two 500 g-weights weigh 1 kg.                      Five 100 g-weights weigh 500 g.

                       2 × 500 g = 1000 g = 1 kg                                5 × 100 g = 500 g

                   Two 250 g-weights weigh 500 g.                       Five 200 g-weights weigh 1 kg.

                            2 × 250 g = 500 g                               5 × 200 g = 1000 g = 1 kg

                            Exercise 10B

                    1.  Convert the following kilograms into grams.

                        a.   4 kg =                g                      b.   6 kg =                g

                        c.   9 kg =                g                      d.   3 kg =                g

                        e.   7 kg =                g                      f.   2 kg =                g

                    2.  Convert the following kilograms and grams into grams.

                        a.   1 kg 200 g =                 g               b.   3 kg 500 g =                 g

                        c.   4 kg 800 g =                 g               d.   5 kg 400 g =                 g

                        e.   6 kg 800 g =                 g               f.   9 kg 76 g =                  g
