Measurement involves determining the size or quantity of something using standardized units. A unit is a fixed quantity that serves as a standard for measurement, such as meters for length, kilograms for mass, and liters for capacity. The document discusses common units used to measure length, mass, capacity, and time, as well as examples like the tallest building in Dubai being 829.8 meters high.

 The tallest building in the world is in Dubai.
 It is 829.8 m high.

5. Mass
 Mass tells us the amount of material an object
contains.
 Weighing balance is used to find the mass of an
object.
 Kilogram is the unit used for measuring mass.
 Smaller masses are measured in grams.
 kg – Kilogram
 g -- gram

6. Capacity
 Capacity of a container is the amount of liquid it can
hold.
 Litre is the commonly used unit for measuring
capacity.
 Smaller amounts of liquid are measured in millilitres.
 l – litres
 ml – millilitres
 A measuring cylinder is used to
measure the amount of liquid.
 Measuring cylinders come in
various capacities.

7. Time
 Time is measured using a clock or a watch.
 The unit for measuring time is seconds.
 We also use minutes and hours as other units.
