Volume

1litre ( l ) = 1 000 mililitre ( ml )

1 litre orange juice

A. Convert litre ( l ) to mililiter ( ml )


1.) 2 litre =( 2 x 1 000 ) mililiter

                = 2 000 mililiter

2.) 5 litre 20 mililitre = ( 5 x 1 000 ) mililitre + 20 mililitre

                               = 5 000 mililitre + 20 mililitre

                               = 5 020mililitre

B. Convert mililitre ( ml ) to litre  (l )

1.) 5 436 mililitre

      = ( 5 436  ÷ 1 000 ) litre

      = 5.436 litre

2.) 780 mllilitre + 6.705 litre

      = ( 780 ÷ 1 000 ) litre + 6.705 litre

      = 0.780 litre + 6.705 litre

      = 7.485 litre

Mass

1 kilogram (kg) = 1000 gram (g)

l kg sugar

A. Convert kilogram (kg) to gram (g) 

1.) 2 kg = (2 x 1 000) g 

             = 2 000g

2.) 5 kg 200 g = ( 5 x 1 000 ) g + 200 g

                       = 5 000 g + 200 g

                       = 5 200 g

3.) 9 kg 345 g + 7 kg 534 g 

     = ( 9 x 1 000 ) g + 345 g + ( 7 x 1 000 ) g + 534 g

     =  9 000 g + 345 g + 7 000 g + 534 g

     = 16 879 g

B. Convert gram (g) to kilogram (kg)

1.) 7 000 g 

         = ( 7 000  ÷ 1 000 ) kg

     = 7 kg

2.)  4 563 g + 1.5 kg

        = ( 4 563 ÷ 1 000 ) kg +1.5 kg

          = 4.563 kg + 1.5 kg

      = 6.063 kg

3.)  8 500 g + 5 kg

      = ( 8 500 ÷ 1 000 ) kg + 5 kg

      = 8.5 kg + 5 kg

      = 13.5 kg

Exercise


1.)  5 kg = (         ) g

2.) 7 kg 550 g = (          ) g

3.) 3 kg 450 g + 2 kg 102 g = (         ) g 
 






4.) 6 500 g = (          ) kg


5.) 3 005 g + 3.2 kg = (           ) kg


6.) 6 700 g + 6 kg = (           ) kg




Answer


1.) 5 000 g

2.) 7 550 g

3.) 5 552 g

4.) 6.5 kg

5.) 6.205 kg

6.) 12.7 kg
