The volume of liquid can be measured using standard or non-standard tools.
Examples of non-standard tools.
Examples of standard tools.
The use of non-standard tools to measure the volume of a liquid is not accurate and not consistent. The appropriate way to measure the volume of a liquid is using standard tools like measuring cylinders, beakers or measuring jugs. There are scales on these containers which determine the volume of liquid.
Can you see the letters ml and on the beaker and the measuring cylinder as shown below?
The volume of liquid is usually measured in metric units that are, litres ( l) and milliliters (ml ).
1 litre = 1000 millilitres
1 l = 1000 ml
Smaller volume of liquid is measured in milliliters (ml ) whereas larger volume of liquid is measured in litres ( l ).
The diagram and the steps below can help you to measure the volume of liquid correctly using a measuring cylinder.
STEP 1
Place the measuring cylinder on a level surface.
STEP 2
Pour the liquid into the measuring cylinder.
STEP 3
Read the volume of the liquid at position B. Your eyes must be level with the lowest part of the meniscus. The volume of the liquid is 50 ml .
Let ‘s read the volume of the liquid.
The volume of the liquid is five hundred milliliters.
We write it as 500 ml .
The volume of the mango juice is one litre.
We write it as 1 l.
The volume of the mango juice is more than the volume of the liquid.
The volume of the liquid is less than the volume of mango juice.
Let’s try it out.
