Water Tank Volume & Weight Formula
Transparent mathematical methodology explained in plain English.
Cylinder Vol (Cu Ft) = π × r² × Height | Gallons = Cu Ft × 7.48052 | Weight (lbs) = Gallons × 8.34 lbs/galCalculates geometrical water volume and structural filled weight (water weighs exactly 8.34 lbs per US Gallon / 1,000 kg per cubic meter).
Variables Explained:
- Tank Shape: Vertical Cylinder or Rectangular Box.
- Diameter / Width (ft): Tank horizontal dimension.
- Height / Depth (ft): Tank vertical height.
6 ft Diameter by 8 ft High Vertical Cylindrical Water Tank
Calculating water storage capacity and structural weight load.
- Cylinder Volume in Cu Ft: π × (3)² × 8 = 3.14159 × 9 × 8 = 226.19 cu ft.
- Capacity in US Gallons: 226.19 × 7.48052 = 1,692 Gallons.
- Capacity in Liters: 1,692 × 3.78541 = 6,405 Liters.
- Filled Water Weight: 1,692 gal × 8.34 lbs/gal = 14,111 lbs (7.06 Tons).
よくある質問 (FAQ): Water Tank Calculator
Click any question below to expand quick answers, formulas, and expert tips.
Why must you calculate water tank filled weight before installation?
Water is extremely heavy (8.34 lbs/gallon). A modest 1,500-gallon tank weighs over 6.25 tons, requiring a reinforced 4-inch concrete slab or compacted gravel foundation to prevent tipping.
How much rainwater can you harvest from a roof?
A 1,000 square foot roof yields approximately 620 gallons of water for every 1 inch of rainfall (1,000 sq ft × 1" × 0.623 conversion factor).
