Displacement help

[osprey23]

Hi I'm hoping someone can help me, if I have the displacement of a boat as a weight, I there a way of converting it to volumetric displacement?
Thanks in advance

Yes, it is called Archimedes' Principle, has been known for some 2200 years and is an essential part of any basic high-school physics course.

Weight = mass * gravity_acceleration
Mass = water_density * Volume

You do the rest.

That will give you different volumes for salt or fresh water and different temperatures

Fresh water weighs around 62.5# a cubic foot, salt water around 64# a cubic foot. Divide the displacement weight by the type of water you're in to find the volumetric displacement. If your boat displaces 10,000 pounds, in fresh water that will be about 160 cubic feet of volume, in salt water, about 156.25 cubic feet of volume.
