Supported Tank Types

Vertical cylinderV = π × r² × h
Horizontal cylinderV = π × r² × l
Rectangular prismV = l × w × h
Vertical capsuleV = π × r² × h + (4/3) × π × r³
Horizontal capsuleV = π × r² × l + (4/3) × π × r³
Vertical ellipticalV = (π × w × h × l) / 4
Horizontal ellipticalV = (π × l × w × h) / 4
Cone bottomV = V_cyl + V_cone
Cone topV = V_cyl + V_cone
Frustum (truncated cone, funnel)V = (π × h / 3) × (R² + R×r + r²)

Partial Fill Calculation

Enter a fill height to calculate the volume of a partially filled tank. Complex circular segment formulas are used for horizontal cylinders.

Unit Conversion

Supports various unit conversions according to the selected unit system (Metric/Imperial).

Calculator Description

The Tank Volume Calculator is an engineering tool that accurately computes the volume of various tank shapes — cylindrical, rectangular, elliptical and conical — which is essential for storage-capacity sizing in industry.

It is used to design and verify tank volumes in water treatment, chemical plants, fuel storage and agricultural reservoirs. Computing surface area alongside volume also helps estimate paint or insulation requirements.

Different mathematical formulas apply per shape, and you can choose metric (m, mm) or imperial (ft, in) units. Specifying a fill height also yields the partially filled volume up to that level, which is very practical.

Accurate volume calculation directly affects cost efficiency and safety. Underestimating leads to insufficient capacity, while overestimating causes unnecessary cost — design on accurate data.

Formula

Cylindrical Tank (Vertical)

V = \pi r^{2} h

V — Volume [m³ or L, etc.]
π — Pi (≈ 3.14159)
r — Radius (Diameter ÷ 2)
h — Height

Rectangular Tank

V = \text{Length} \times \text{Width} \times \text{Height}

Conical Tank

V = \dfrac{1}{3}\,\pi r^{2} h

Partial fill & units

Entering a fill height returns the volume up to that level. Horizontal cylinders use circular-segment integration, and units convert between m³↔ft³ and L↔gal per the selected system.

Useful Tips

Tank Type Selection Guide

Vertical Cylindrical: Most common; withstands high pressure well
Horizontal Cylindrical: Good where height is restricted
Rectangular: Advantageous for custom installation spaces
Cone Bottom: Suitable when sediment discharge is needed

Volume Unit Conversion

1 m³ = 1,000 Liters (L)
1 Liter = 0.001 m³
1 gal (US) ≈ 0.003785 m³

⚠️ Precautions

When actually manufacturing a tank, add about 5–10% of the calculated volume as margin for wall thickness, weld seams, thermal expansion, etc.

Real-life Application Examples
