Tank Volume Calculator A1 PRO

Tank Volume Calculator is a professional engineering tool for calculating the volume, weight, and fill level of tanks and containers across 24 unique shapes.

Whether you're an engineer sizing industrial storage tanks, a contractor estimating concrete volumes, or a farmer calculating water tank capacity — this app gives you instant, accurate results without manual formula lookups.

— 24 TANK SHAPES —

Calculate volumes for shapes including:
• Vertical & Horizontal Cylindrical Tanks
• Rectangular Tanks (standard & sloped bottom)
• Spherical & Hemispherical Tanks
• Conical & Frustum Cone Tanks
• Capsule Tanks (horizontal & vertical)
• Elliptical Tanks (horizontal & vertical)
• Hexagonal & Octagonal Prism Tanks
• Pyramidal & Inverted Pyramid Tanks
• L-Shaped Tanks
• Horizontal Oval (Stadium) Tanks
• And more

— PARTIAL FILL CALCULATIONS —

Don't just calculate total volume — enter the current fill height to instantly compute:
• Occupied volume (how much is in the tank)
• Empty volume (remaining capacity)
• Fill percentage (%)
• Weight of material based on density

— MATERIAL DENSITY DATABASE —

Built-in searchable database of material densities displayed in both kg/m³ and lb/ft³. Select a material and the app automatically calculates the weight of the liquid or material in your tank. Pro users can add, edit, and delete custom materials.

— 4 UNIT CONVERTERS —

Convert between common engineering units in one tap:
• Density: g/cm³, kg/m³, kg/L, lb/ft³, lb/gal, oz/in³
• Volume: Liters, mL, cubic inch, cubic foot, cubic meter, US gallons
• Length: Meters, centimeters, millimeters, feet, inches
• Temperature: Celsius, Fahrenheit, Kelvin

— SCIENTIFIC & CONSTRUCTION CALCULATOR —

Two calculator modes built for professionals:

Scientific: sin, cos, tan, log, ln, sqrt, power, pi, memory, parentheses, and more.

Construction: Store Length, Width, and Height values, auto-compute area and volume, calculate diagonals, estimate material costs with a rate/price function, and perform mixed-unit arithmetic (e.g., "5 m + 3 ft" auto-converts).

Includes a paper tape history to review, label, and share past calculations.
