Units for The Measurement of Capacity

We know that the two main units for the measurement of capacity are liter and milliliter. In short liter is written as 'l' and milliliter as 'ml'.

As for measuring mass we have made several measures to weigh the different masses as 1kg, 500g, 250g, 200g, etc. Similarly, for measuring different capacities there are several different shaped liter-measures and milliliter measures.

There are different types of shaped vessels having one liter capacity and there are some measures greater than 1 liter capacity are 2 l, 5 l and 10 l.

There are some small measures in ml to measure small quantities of liquid. Some such measures are 500 ml, 200 ml and 100 ml.

In the market and at home we may see some vessels of 10 liters and 15 liters capacity in cylindrical or cuboid shapes. There are different types of drums having 100 liters capacity.

We know that 1 litre = 1000 milliliters (1 l = 1000 ml)

So,               500 ml = 1/2 of a litre

                    250 ml = 1/4 of a litre

                    200 ml = 1/5 of a litre

                    100 ml = 1/10 of a litre

If we have to measure 300 ml of a liquid, we use the measures of 200 ml and 100 ml capacities. To measure 700 ml of a liquid, we use the measures of 500 ml and 200 ml.

We know that capacity is the amount of liquid which a container can hold. The basic units of measurement of capacity are liter (l) and milliliter (ml). To measure smaller quantities of liquid, we use milliliter (ml) and to measure larger quantities we use liter (l). We can convert l to ml by multiplying the number of liters by 1000 and milliliters (ml) to liter (l) by dividing the number of milliliters by 1000.
