Frequently Asked Questions
What is the difference between a litre and a millilitre?
A litre is used to measure large amounts of liquid like a bucket of water, while a millilitre is used for very small amounts like cough syrup in a spoon.
How many small glasses of water fill one big jug?
The number of glasses depends on the size of the glass and the capacity of the jug, which is tested by counting how many times a small container is used to fill a larger one.
Why do we use standard units like litres instead of cups?
Cups and glasses come in different sizes, so standard units like litres give an exact and universal measurement that everyone can understand.
