Rectangular Tank Volume & Capacity
Calculate full and filled capacity for a rectangular tank from internal dimensions and fill percentage.
💡 Engineering Knowledge PrimerRectangular tank capacity is the internal footprint multiplied by the internal height. Reporting both full and filled volume makes the result useful for process-water storage, chemical batching, utility tanks, and transfer-pump planning without implying a vessel design check.
OPERATING LIMITS — Geometric capacity calculation only; verify internal dimensions, freeboard, usable volume, fittings, baffling, structural rating, and applicable vessel requirements.

Technical Methodology & Engineering Principles
GOVERNING EQUATION
Full volume V = L × W × H
Filled volume = V × (Fill % / 100)
Assumptions & Scope
Internal rectangular dimensions; uniform liquid depth; no allowance for walls, fittings, baffles, dead zones, or freeboard beyond the entered fill percentage.
Operating Range & Boundary
Dimensions must be positive and fill level must be between 0% and 100%.
