In SI units, it would be Liters. In Imperial units, it would be Gallons.
Liters would be the metric measurement for volume of liquid.
Miles, kilometers, meters, yards, grams, kilograms
a bath tub is a milliliter because a liter is the size of a water bottle
You could immerse it in a liquid, and measure the volume of the displaced liquid.You could also use integration techniques.You could immerse it in a liquid, and measure the volume of the displaced liquid.You could also use integration techniques.You could immerse it in a liquid, and measure the volume of the displaced liquid.You could also use integration techniques.You could immerse it in a liquid, and measure the volume of the displaced liquid.You could also use integration techniques.
If you mean what means does one have to measure it, the best tool is "displacement": You take a known volume of water, and immerse the thing you want to measure. The amount of extra space the water takes up will be exactly the volume of the thing you put in it.
Immerse it in water and its volume is equal to the volume of water displaced
Push it down, and measure how much water is displaced.
How could you determine your mass using water, a bathtub,something to measure water with, and Archimedes' princilpe?
That depends upon the volume of the object that is put into the water in the bathtub.

Which unit would you use to measure the water in a full tub?
Use the water displacement method

The instrument you would use could be a beaker or a graduated cylinder.
It is the volume of water that the tub can hold until the water reaches the overflow hole.
Take a container with a rather precise scale and measure it. Place the ring inside and measure it again. The amount the water goes up is the volume of the ring. Or you could fill a container to the brim with water, with a collecting dish underneath. Put the ring in the container, which would cause some of the water to overflow. The volume of water that left the container is the volume of the ring. Or you could take a clay mold and make a mold of the ring, fill that with water and measure how much water it takes to fill the 3D mold.
