Torus Volume Table: Volume by Major radius (R, centre to tube centre)

Reference table of volume for Torus Volume across a range of major radius (r, centre to tube centre) values — exact, engine-computed figures you can read off at a glance.

By Vikram Iyer, M.Sc Mathematics · Updated Jun 2026 · 1 min read

This torus volume reference table shows the volume for a range of major radius (r, centre to tube centre) values, assuming a minor radius (r, tube radius) of 2 units. Every figure is computed with the same engine that powers our Torus Volume Calculator, so the numbers are exact.

How to use this table

Find the row closest to your major radius (r, centre to tube centre) and read across to the volume. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Torus Volume Calculator for a precise answer.

Need a value that is not in the table? — the Torus Volume Calculator does it instantly, for free, with the formula and a worked example built in.
