Tank Volume Calculator

Interpreted per the measurement selector above.
For a horizontal tank or a pipe this is the run length.
Only affects the partial-fill calculation.
Depth of liquid: measured up the wall when vertical, across the diameter when horizontal.
Material density for a solid/hollow body, or contents density for a tank.

No fill depth entered, so the figure shown is the full capacity of the tank.

How this is worked out

5 steps
  1. Outer radius R = 1 ft, height/length h = 5 ft
  2. Volume V = pi r^2 h = pi x 1 x 5 = 15.707963 ft^3
  3. Curved surface = 2 pi R h = 31.415927 ft^2
  4. Total surface = curved + 2 x end face = 31.415927 + 2 x 3.1415927 = 37.699112 ft^2
  5. Capacity in US gallons = 117.50373; in litres = 444.79999.
