1 litre = 1000 ml


            Conversion


            Observe the given examples carefully.


            Example :            2 l  =         2 × 1000 ml = 2000 ml

                                 3 l  =         3 × 1000 ml = 3000 ml                    Always multiply

                                                                                       by 1000 to convert
                                 4 l  =         4 × 1000 ml = 4000 ml
                                                                                              l into ml.
                                 5 l  =         5 × 1000 ml = 5000 ml





            Example :            8 l + 250 ml          =      8 × 1000 ml + 250 ml = 8250 ml


                                 9 l + 685 ml          =      9 × 1000 ml + 685 ml = 9685 ml

                                 2 l + 84 ml           =      2 × 1000 ml + 84 ml = 2084 ml



            Addition and Subtraction of Capacity



            The process of addition and subtraction is measures of capacity is the same

            as that of natural numbers.

            Example :            Add the following.



                           ml                                 ml                            l             ml


                        5  3  6                            2  4  5                         4  4        3  7  5


                    +   2  4  5                      +     3  6  7                  +      8  1        9  6  8


                        7  8  1                            6  1  2                       1 2 6         3  4  3





                     \ 781 ml                       \ 612 ml                           \ 126 l 343 ml
