The weight of a given quantity of a liquid depends on the specific gravity of the liquid.
The specific gravity of a liquid is the ratio of the density of the liquid - to the density of water at 4 deg C.
That is why most oil floats on water, it has a lower specific gravity and (as an example often used) carbon tet sinks because it has an SG of around 1.6.

All liquids are a fluid but all fluids are not a liquid.

However when fluid is used as a noun and describes the "phase" of a material, most have three phases, it's a different thing entirely.
The context in which you used "liquid" was plainly as a noun.
