Because it's the ratio of two densities ... the density of the substance of interest
to the density of water.
In any ratio, the units of both quantities are the same, so the ratio winds up being
a dimensionless number.
because
unit of specific gravity is maas/cubic meter so same units are cancelled out

There is no such thing as a specific gravity for any element.
Head pressure=specific gravity*1000*gravity*height. Therefore if specific gravity is increased head pressure will increase.
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
Specific gravity is the density of a substance, divided by the density of water. Since two units of the same type are divided, specific gravity is dimensionless (i.e., no unit).
"Dimensionless" means it doesn't have a unit.
I just learned about this in chem11. I'll give the definition off my sheet. Specific gravity is a dimensionless unit defined as the ratio of density of a material to the density of water at a given temperature (usually at 4oC). Note that this expression is obsolete today; use the density.
Angles are not dimensionless.
Volume = mass / specific gravity. Units are cubic centimeters and grams or cubic meters and tonnes. s.g. has no units : it is a dimensionless quantity.
The unit weight of soil with a specific gravity of 2.65 is 1.8 g/cc.
If a quantity is "dimensionless", that means it has no units, and it's just a number.
Specific gravity doesn't have units. It's the density relative to water, so specific gravity is effectively just a number.

Relative permeability is dimensionless
It is a dimensionless parameter since its just a ratio between two quantities of same unit.
A dimensionless unit - an integer (or counting number)!
