    Measurements

Measurement

We use scale to measure small lengths. We use a measuring tape to measure bigger lengths.
For example, a hockey stick is about 1 meter long.
Centimeter,meter, and kilometer are the most used units of length.

Conversion of units of length

    Conversion of meters into centimeters.

    A meter is a larger unit than a centimeter.
    1 m=100 cm

    How many cm are there in 3 m.
    3m = 1 m +1 m+1 m = 3× 1 m= 3×100 cm= 300 cm.

    •Example:Convert 7 m into centimeters.
    7 m= 7× 1 m = 7×100 cm= 700 cm.

    •Example 2:Convert 8 m 15 cm into centimeters.
    8 m 15 cm= 8 m+ 15 cm
    = 8×100 cm + 15 cm
    =800 cm + 15 cm= 815 cm.

    •Example: Convert 800 cm into meters.
    800 cm=(800÷100)m=8m
    Answer = 8 m.

Measuring Distances

    Ravi takes both dogs for a walk every day.
    Ravi takes the dogs along for a distance of 4 kilometers.
    What is a kilometer?
    It is a unit used to measure long distances like the distance between two cities or towns.

    1000 meters=1 kilometer.
    4 kilometers = 4 × 1000meters =4000meters
    4000meters = 4km
    In short, kilometer is written as km.

    Measuring Weight(Or Mass)

    •Sachin had gone to buy meat for the dogs to eat. He bought 600 gm of meat for Dido and 400 gm for Dullu. How many kilograms did he buy in all?
    •We use a weighing balance to find out the weights of objects.
    A fruit and vegetable seller or a grocer uses standard weights to weigh objects. Generally, he keeps weighs of 5 kgs, 2 kg, 1 kg, 500g, 200g, 100g and 50g.

    measurements

    1kg=1000g =500g+500g.

    There are different combinations by which we can make a kilogram.
    1kg=1000g
    1kg=500g+500g
    1kg=200g+200g+200g+200g+200g
    1kg=100g+100g+100g+100g+100g+100g+100g+100g+100g+100g

    Measuring Capacity

    Tommy and Johny were drinking milk from their bowls. Johny loved milk but Tommy did not.
    Dolly gives 750 milliliters of milk to Johny and 250 milliliters of milk to Tommy. How much milk does she give the dogs in all?
    Milliliter is written as ml.

    + TH H T O
    1 71 5 0
    2 5 0
    1 0 0 0
    Dolly gives 1000 ml of milk to the two dogs together.

    1000 ml=1 liter.
