Litres and Millilitres
What are litre (liter) and millilitre (milliliter)?
Litre (l) and millilitre (ml) are units of volume and capacity.
1 l = 1000 ml
Or,
1000 ml = 1 l
1 l = 1000 ml
Or,
1000 ml = 1 l
1. Angela has a bottle filled with milk to the brim.
She empties the bottle into the following measuring cups.
Find the capacity of the bottle in litres and millilitres.
![litres and millilitres](/images/P3ProblemImages/P3LMLitresMilli_milk_1280.png)
Volume of milk in the 1st cup = 1000 ml
Volume of milk in the 2nd cup = 100 ml
Volume of milk in the 3rd cup = 100 ml
Volume of milk in the 4th cup = 80 ml
Total volume of milk in the 4 cups
= 1000 ml + 100 ml + 100 ml + 80 ml
= 1280 ml
= 1 l 280 ml
The capacity of the bottle is 1 l 280 ml.
Volume of milk in the 2nd cup = 100 ml
Volume of milk in the 3rd cup = 100 ml
Volume of milk in the 4th cup = 80 ml
Total volume of milk in the 4 cups
= 1000 ml + 100 ml + 100 ml + 80 ml
= 1280 ml
= 1 l 280 ml
The capacity of the bottle is 1 l 280 ml.
2. A container has 1 l 625 ml of juice.
Express the volume of juice in the container in millilitres.
The amount of juice in a container is called the volume of juice in the container.
We know,
1 l = 1000 ml
1 l 625 ml
= 1 l + 625 ml
= 1000 ml + 625 ml
= 1625 ml
The volume of juice in the container is 1625 ml.
1 l = 1000 ml
1 l 625 ml
= 1 l + 625 ml
= 1000 ml + 625 ml
= 1625 ml
The volume of juice in the container is 1625 ml.
3. A flask has 4 l 50 ml of chemical in it.
Express the volume of chemical in the flask in millilitres.
We know,
1 l = 1000 ml
So,
4 l = 4000 ml
Hence,
4 l 50 ml
= 4 l + 50 ml
= 4000 ml + 50 ml
= 4050 ml
The volume of chemical in the flask is 4050 ml.
1 l = 1000 ml
So,
4 l = 4000 ml
Hence,
4 l 50 ml
= 4 l + 50 ml
= 4000 ml + 50 ml
= 4050 ml
The volume of chemical in the flask is 4050 ml.
4. Mr. Thomas filled 3004 ml of water in a pail.
Find the volume of water in the pail in litres and millilitres.
We know,
1000 ml = 1 l
So,
3000 ml = 3 l
Hence,
3004 ml
= 3000 ml + 4 ml
= 3 l + 4 ml
= 3 l 4 ml
Volume of water in the pail is 3 l 4 ml.
1000 ml = 1 l
So,
3000 ml = 3 l
Hence,
3004 ml
= 3000 ml + 4 ml
= 3 l + 4 ml
= 3 l 4 ml
Volume of water in the pail is 3 l 4 ml.
