## What is Tank Volume & Dip Chart?

▶ Find any tank's real capacity in seconds. Choose a shape — horizontal or vertical cylinder, rectangular, oval or capsule — enter the dimensions, and get the total in gallons, liters or barrels.

▶ Read the level, not a guess. Enter a dipstick reading and the app shows the current volume and percent full, with a cross-section gauge that fills as the level rises.

▶ Print a dipstick chart. Generate a full level-to-volume table at your chosen step, then share or print it to tape on the tank — the killer feature for farm fuel, water and septic tanks.

▶ Save your tanks. Keep diesel, water and cistern tanks in one list and reopen any of them instantly.

▶ Works offline, no account needed.

Results use standard geometry and are estimates; tank walls, fittings and manufacturing vary. When a maker's chart exists, follow it first.
