Density of water = 1000kg/m3.
The specific gravity of water = 1.
How is 1 numerically equal to 1000.
Answer = False.

Why to discuss water only?
Fluid name is not mentioned. What about other fluids?
So it must be false right?

It's only for gm/cc3.

As we know density of water is 1000kg/m^3.
Spc. Gravity=density of any fluid/density of water;
S.g=density of any fluid/1000kg/m^3.
Ex:-sg of water is 1 ...mercury 13.6.
The density of water 1000kg/m^3.
S.g of water=1000/1000 = 1.
So, here the kg/m^3 is numerically is equal to s.g.

Unit should be gram/cm^3.

The assertion is incorrect since density is expressed in kg/m3. If the density was provided in gm/cc, then the statement could have been accurate, as the specific gravity of a fluid is equal to its density in gm/cc.

Density of liquid = it's specific gravity * 1 gram/m^3.
= 1000kg/m^3.
= 1000kg/m^3.

Sg has no unit.
That's why The specific gravity of pure water is taken as unity.

Specific gravity says that's used fluid is how time in weight of tested fluid(water).
So it can't say that the density May equal to the specific gravity.
So answer will be B correct.
So it can't say that the density May equal to the specific gravity.
So answer will be B correct.

@Brij kishor. According to your answer, there should be proportional not numerically equal.
