Tank Volume & Liquid Weight Calculator
Calculate partially filled rectangular or cylindrical tanks, US and imperial gallons, liquid mass and current or full gross mass.
About this tank volume & liquid weight calculator
Calculate partially filled rectangular or cylindrical tanks, US and imperial gallons, liquid mass and current or full gross mass Computes exact algebraic and numerical metrics directly in your browser using IEEE 754 precision without round-trip latency.
Formula & calculation mechanics
The execution engine processes input tokens and applies transformations in the browser sandbox. Specifically, Use internal dimensions and flat ends. Rectangular and vertical cylinders fill linearly with height; a horizontal cylinder uses the circular segment area times its axial length. Gross mass adds tank and other fixed mass to liquid mass. Full gross mass always assumes 100% filled.

Domain range & precision boundaries
Use decimal points or scientific notation, up to 64 characters per field. Dimensions: 1e−9 to 1e9 in the selected unit; density: 1e−9 to 1e9 kg/L; fixed mass: 0 to 1e30 kg; rated total load: greater than 0, up to 1e30 kg, or blank. The comparison uses your supplied total mass rating, in kg, for both current and full loading. A blank rating means not assessed. Below the rating is not a safety approval. Include gravel, equipment and other fixed masses; verify the tank, stand and floor separately. No structural strength or pressure calculation is performed. Level rigid tanks only; no domed ends, tilt, wall thickness, internal displacement, thermal expansion or dynamic loads. Binary64 arithmetic and up to 12 displayed significant digits; tiny values may round to zero. Kilograms denote mass, not force. Extreme dimensions are mathematical extrapolations.
Calculations in Tank Volume & Liquid Weight Calculator use standard IEEE 754 precision or exact rational models. Verify significant accounting or tax figures with authoritative references.

Frequently asked questions
Tank Volume Calculator calculation method and limits+
Use internal dimensions and flat ends.
How does Tank Volume Calculator configure shape?+
Liquid height is 0–100% of internal height, or of diameter for a horizontal cylinder. It is not the volume percentage. Water defaults to approximately 1 kg/L; enter the density at your actual conditions.
Current gross load+
Runtime handling of "Current gross load" executes synchronously in your browser tab without remote delays.
Dimension unit+
1 US liquid gallon = 3.785411784 L; 1 imperial gallon = 4.54609 L. Both outputs refer to the current liquid volume.
