    Exercise 10A

                        1.  Write the correct unit (kg, mg or g) used to weigh the following objects.

                           a.                       b.                        c.                       d.

                           e.                       f.                        g.                       h.

                                 _________                _________                _________                _________

                       2.  Collect the following  things from your surroundings and estimate their weights by
                           holding them in your hand. estimate and write whether the given objects weigh more
                           than 1 kg or less than 1 kg.

                           a.                       b.                        c.                       d.

                                                                                                    21 st

                                                                                                   Skills
                    The following relationships between the units of weight are helpful in conversion.

                                          1 kilogram = 1000 grams              or  1 kg = 1000 g
                                              1 gram = 1000 milligrams  or            1 g = 1000 mg

                    Kilograms into grams

                    To convert kilograms into grams, we multiply the number of kilograms by 1000 and
                    put g to the right of the product.
                    examples:  a.  9 kg = (9 × 1000 ) g = 9000 g                   b.  4 kg = (4 × 1000 ) g = 4000 g

                                                                                                                 163
