Question

Here, 1 litre is equal to how many ml?

Answer 1

In the above given question, we are given an amount of one litre. The unit of litre is denoted by the letter L. We have to determine how much amount it becomes when we measure the amount in the units of millilitres, that is denoted by suffix ml. These two units, namely the litre and millilitres respectively, are the units of volume. The word “milli” in millilitre stands here for the thousandth part of its succeeding unit that is a litre. In other words, one millilitre is actually the thousandth part of a litre.

Complete answer: :
We are given an amount of volume that is $1$ litre or $1$ L.
We have to determine the above given amount in the units of millilitres i.e. ml.
In order to approach the solution, we have to use the method of unit conversion from the units of litre to millilitres.
Now since, we know that one millilitre is the thousandth part of a litre,
Hence, mathematically we can write it as,
$\Rightarrow 1ml = \dfrac{1}{{1000}}l$
Therefore, above information implies that an amount of volume of $1000$ millilitres is equal to the amount of volume of $1$ litre.
Or, mathematically we can write it as the equation,
$\Rightarrow 1000ml = 1l$
That is,
$\Rightarrow 1l = 1000ml$
That is the required relation between the two units of volume which are litre and millilitre.
Therefore, $1$ litre is equal to $1000$ millilitres .

Note:
However, the two measurement units, litre and millilitres are both the two different measuring units for volume, but the standard unit for the measurement of volume i.e. the S.I. unit of volume is cubic metres denoted by the symbol ${m^3}$ . The volume one cubic metres is equal to the volume of a thousand litres.
Mathematically, we have
$\Rightarrow 1{m^3} = 1000l$
