The density of a substance is the ratio of its mass to its volume. So, I would measure the mass and volume of a substance to calculate density.

to for example measure the pressure under water
Measure the container itself, or measure the mass of the liquid and the container and find the density of that certain liquid has and isolate for the volume.
The units for density are mass / volume; in the SI, that would ideally be kilograms / cubic meter.
Since density is mass / volume, the natural SI unit is kilogram / cubic meter.
water.
That depends what you want to measure about it: its weight, its color, its density, etc.
g/cm3
They would use density to measure the volume of a substance :)

you would use a scale to measure the mass and a beaker to measure the volume. i need another tool
It depends on whether you want to measure its length, its width, its mass, its colour, its density etc.
You can look up the density of different materials in a table of densities. But if you want a formula, just use the definition of density as mass / volume. This is also how you would measure the density of a substance of unknown density.
Usually the density of an object is measured by immersing the object into water and then measuring the volume of the water. So no calculator would be required.
Mass divided by volume

Yes, we can use hydrometer to measure the density of milk. Explanation Hydrometer is a device which is used to measure the density of a liquid. Hydrometers are calibrated for different uses, such as a lactometer for measuring the density (creaminess) of milk, a saccharometer for measuring the density of sugar in a liquid, or an alcoholometer for measuring higher levels of alcohol in spirits
