MEASUREMENT - CONVERSION FROM BIG UNIT TO SMALL UNIT

EXPLANATION FOR CONVERSION FROM BIG UNIT TO SMALL UNIT :-

▪  Write the short table from gram to centigram.

▪  Fill up the given values.

▪  The remaining units are filled up with zeroes.

▪  Multiplication By 10, 100, 1000 is done by shifting the decimals point to the right of the given number.

All the values together gives the answer

There are some examples are given below for your better understanding -


Example.1) Convert 215 grams into centigrams. (When we convert Bigger to smaller unit => multiply)

Ans.)   Given number unit is 872 g

             g     dg     cg

            215     0      0    =   21500 cg        


                            - ALTERNATELY -

1 gram = 100 centigrams

215 grams = 215 x 100    [SHORT MULTIPLICATION]

            = 21500 cg    [ADD 2 ZEROES AT THE END TO MULTIPLY]

                                           (Ans.)



Example.2)  157 kg 25 g into grams

Ans.) Given number unit is 157 kg 25 g

       kg       hg      dag     g      

       157       0        2       5      =  157025 cg


                                        - ALTERNATELY -

1 kilogram = 1000 grams

157 kilograms 25 grams = 157 x 1000 g + 25  [SHORT MULTIPLICATION]

                = 157025 grams  [ADD 2 ZEROES AT THE END TO MULTIPLY]                                (Ans.)
