I build free online math tools. My project is the Cylinder Volume Calculator — a free tool that computes the volume of a cylinder (V = πr²h) with radius, diameter and height inputs, hollow-cylinder math, unit conversion, formulas and worked examples for students, engineers and DIYers.

One more thing worth doing before you buy is to sanity-check the tank's stated capacity yourself. Since most household tanks are cylindrical, measuring the inner diameter and height and working out the [volume of cylinder](https://www.cylindervolume-calculator.com/) (πr²h) tells you the real usable volume in litres. It only takes a minute and helps you compare models fairly instead of relying on advertised numbers alone.
