                                                   REMEMBER!
                               Mass measures the amount of matter in an object.
                         The units gram (g) and kilogram (kg) are used to measure mass.
                                                  1 kg = 1000 g
                         Capacity measures the amount of liquid a container can hold.
                      The units litre (L) and millilitre (mL) are used to measure capacity.
                                                   1 L = 1000 mL
