The most comprehensive tank volume calculator on the market — supporting 30+ tank shapes with professional-grade engineering accuracy.
Whether you're an engineer designing storage systems, a contractor estimating capacity on-site, or a logistics professional calculating shipping volumes, this app gives you instant, accurate results.
▸ 30+ TANK SHAPES
Calculate volume for cylindrical, rectangular, spherical, conical, elliptical, hexagonal, octagonal, pyramidal, capsule, frustum, L-shaped, and many more tank configurations — including horizontal and vertical orientations.
▸ PARTIAL FILL CALCULATIONS
Don't just calculate full capacity — enter the current fill height to get occupied volume, empty volume, and percentage filled. Essential for inventory monitoring and tank gauging.
▸ WEIGHT FROM VOLUME
Select a material from the built-in density database and instantly convert volume to weight. Perfect for calculating liquid loads, material quantities, and shipping weights.
▸ SCIENTIFIC & CONSTRUCTION CALCULATOR
Two powerful calculator modes:
• Scientific — sin, cos, tan, log, ln, sqrt, powers, memory (M+/MR)
• Construction — store Length/Width/Height, auto-calculate area & volume, diagonal, unit buttons for m, ft, cm, in, m², ft², m³, ft³, liters, and more
▸ MATERIAL DENSITY DATABASE
Searchable reference library of material densities in kg/m³ and lb/ft³. Pro users can add, edit, and delete custom materials.
▸ UNIT CONVERTER
Convert between length (m, cm, mm, ft, in), volume (m³, ft³, liters, gallons), density (kg/m³, lb/ft³), and temperature units — all in one place.
▸ STUDY & REFERENCE
Built-in formula reference with detailed explanations for every tank shape, unit conversion tables, measurement guides, and partial fill theory. Learn while you calculate.
▸ SAVE & EXPORT
Save calculations for later, export results as PDF, and share via any app. Label your saved calculations for easy retrieval.
▸ FAVORITES
Bookmark your most-used tank shapes for quick access from the home screen.
▸ DARK MODE & 6 LANGUAGES
Comfortable viewing in any lighting. Available in English, Hindi, Spanish, Portuguese, Arabic, and Turkish.
▸ WORKS OFFLINE
All calculations run locally — no internet required. Take it to the field, the factory floor, or the classroom.
