| Diameter (D) | Measurement or estimation (in meters or feet) | Diameter of the tank |
| Height (H) | Measurement or estimation (in meters or feet) | Height of the tank |
| Thickness (T) | Usually a known value or design specification | Thickness of the tank walls |
| Material Density (ρ) | Known material density (kg/m³ or lb/ft³) | Density of the material the tank is made from |
| Volume (V) | π * (D² / 4) * H | Volume of the cylindrical tank |
| Surface Area (A) | π * D * H | Surface area of the cylindrical tank |
| Inner Diameter (Di) | D – 2*T | Inner diameter of the tank (subtracting wall thickness) |
| Outer Diameter (Do) | D + 2*T | Outer diameter of the tank (adding wall thickness) |
| Inner Surface Area (Ai) | π * Di * H | Inner surface area of the tank |
| Outer Surface Area (Ao) | π * Do * H | Outer surface area of the tank |
| Inner Volume (Vi) | π * (Di² / 4) * H | Volume of the inner cylinder (without wall thickness) |
| Outer Volume (Vo) | π * (Do² / 4) * H | Volume of the outer cylinder (with wall thickness) |
| Inner Wall Weight (Wi) | Vi * ρ | Weight of the inner wall material |
| Outer Wall Weight (Wo) | Vo * ρ | Weight of the outer wall material |
| Total Tank Weight | Wi + Wo | Total weight of the tank |
