1kg water is equal to 1 litre. Is 1 kg of milk equal to 1itre milk?If not then what is the relation?

No, 1 kg of milk is not equal to 1 litre of milk.

To find out the volume of 1 kg of milk, let us take help of the following relation between density, mass and volume.

Density = Mass / Volume

=> Volume = Mass / Density

Density of milk - 1033kg/m31033kg/m3

Mass of milk - 1kg1kg

=> Volume = 1kg/1033kg/m31kg/1033kg/m3

=> Volume = 0.000968054211m30.000968054211m3

Now, 1m3=1000l1m3=1000l

=>0.000968054211m3=(0.000968054211∗1000)l=>0.000968054211m3=(0.000968054211∗1000)l

=>0.000968054211m3=0.968l=>0.000968054211m3=0.968l

or,0.000968054211m3=968ml
