(b) Use the relationship between grams and kilograms.

                     1000 g    = 1 kg

                      6  ×          = 1000 g  6  ×  1 kg
                                      = 6 kg

                1.  Convert the following measurements:
                     (a) 89 kilograms into grams
                     (b) 58,000 grams into hectograms
                     (c) 6,500 kilograms into tonnes
