Have you ever wondered why some cultures think it is important to have a last name?

It shows their identity and defines their relationship with their forefathers or ancestors.

Similarly, we associate quantities of certain items with their units.

For example, length has meter, volume has litre, time has seconds, and so on.

In this chapter, we will be converting litres to millilitres.

Lesson Plan

Define Litres and Millilitres


A litre is a basic metric unit that represents the volume.

It is used to measure liquids. 

A litre is denoted with an abbreviation l or L and is measured as \(\ L^3\).

A litre is slightly more than a quart.

The water pitcher below has exactly 1 L of water in it.

1 litre = 1000 ml


A millilitre is a smaller metric unit that represents the volume or capacity.

It is used to measure a smaller quantity of liquid.

A millilitre is denoted with an abbreviation ml or mL and is measured as \(\ mL^3\).

The water pitcher below has exactly 1,000 mL of water in it.

1000 ml =1l

A standard Pasteur pipette or an eyedropper holds 20 drops which is equal to 1 mL.

pipette measures in millilitre

These bottles can fill up to 200 ml of milk.

1. Using the unit converter, find the value of the following:

a) \(\ 1,000\ mL = \underline{?} kL\)
b) \(\ 1,000\ mL = \underline{?} cL\)
c) \(\ 1,000\ mL = \underline{?} Litre\)
d) \(\ 1,000\ mL = \underline{?} hectaLitre\)
e) \(\ 1,000\ mL = \underline{?} deciLitre\)

Solved Examples

Example 1



Convert the following.

a) 25 L to mL
b) 18 L to mL
c) 13 mL to grams
d) 1 Litre to kg


a) \(\ 25\ L = 25\times 1,000 = 25,000\ mL\)

b) \(\ 18\ L = 18\times 1,000 = 18,000\ mL\)

c) \(\ 13\ mL = 13\times 1 = 13\ g\)

d) \(\ 1\ L = 1\times 1 = 1\ kg\)

\(\therefore\) \(\begin {align}25\ L &= 25,000\ mL\\
18\ L &= 18,000\ mL\\
13\ mL &= 13\ grams\\
1\ L &= 1\ kg\end{align}\)

Example 2



Joe purchased a hand sanitizer. 

The bottle contains 2,500 mL of liquid content.

How many litres of the liquid does this sanitizer bottle contain? 

litre to millilitre


\[\ 2,500\ mL = \frac{2,500}{1,000} = 2.5\ L\]

\(\therefore\) Sanitizer bottle contains 2.5 L

Example 3



Ross bought 3 cans of orange juice of 1 L each.

He drank 1,500 mL of juice.

How much mL of juice is remaining in the cans?

litre to millilitre


\[\begin{align} 1\ can &= 1\ L\\3\ cans &= 3\ L\\ &= 3\times 1,000 = 3,000\ mL\\ &= 3,000\ mL - 1,500\ mL\\ &= 1,500\ mL\end{align}\]

\(\therefore\) 1,500 mL of juice is remaining.

Frequently Asked Questions (FAQs)

1. Is 1 L the same as 750 mL?

No, \(\ 1\ L = 1,000\ mL.\)

\(\ 750\ mL = \frac{750}{1,000} = 0.75\ L \)

2. Is 1 L the same as 1000 mL?

Yes, \(\ 1\ L = 1,000\ mL \)

3. How many litres are in 80 mL of liquid?

\(\ 1\ L = 1,000\ mL\)

Thus, \(\ 80\ mL = \frac{80}{1,000} = 0.08\ L \)
