Method
The selected ideal-solid formula is applied: products of dimensions for prisms, πr²h for cylinders, and the corresponding exact geometric identity for curved solids.

Volume Calculator
Calculate the volume of a box, cylinder, sphere, cone, cube, capsule, ellipsoid, square pyramid or conical frustum.
The calculation runs locally. Exact-integer tools avoid floating point; decimal and transcendental tools report rounding limits.

How the Volume Calculator works
The selected ideal-solid formula is applied: products of dimensions for prisms, πr²h for cylinders, and the corresponding exact geometric identity for curved solids. The calculator keeps the intermediate values visible so you can reproduce the answer independently.
Interpret the result
Cubic units scale with the cube of the chosen length unit; doubling every dimension multiplies volume by eight.
Check the assumptions
These are ideal external geometries. Real container capacity can differ because of wall thickness, tolerances and irregular surfaces.
Local calculation
Everything runs in this browser. Inputs are not sent to an external calculator.
Rounding
Displayed values may be rounded for readability while calculations use full floating-point precision unless the tool explicitly uses exact integers.
Scope
These are ideal external geometries. Real container capacity can differ because of wall thickness, tolerances and irregular surfaces.
Simple by design
Three steps to a clearer number.
Enter your details
Use realistic values in each field. You can change them anytime.
Calculate instantly
The formula runs locally, so there is no account or waiting time.
