We  use  some  weights and  a  weighing  balance to  weigh  the  mass  of an
               object.


                                                                        5 kg

                                                                    500 g         200 g        100 g      50 g

                                              Units of Volume (Capacity)


               We have already learnt that the amount or volume of liquids is measured in
               millilitre (mL) and litre (L). The unit litre (L) is the standard unit of capacity.

               The unit millilitre is the smaller unit of capacity. It is 1000 times smaller
               than a litre.


               i.e.,                         1 L = 1000 mL

                                                        1
               or                          1 mL =             L = 0.001 L
                                                      1000

               We  use  different  types  of  containers  or  vessels  to  measure  the  capacity
               of  liquids.  Some  of  the  commonly  used  measuring  containers  are  shown

               below.

                   used in laboratories.                            for commercial purposes.
