Aquarium Capacity Calculator

Depth of liquid measured from the lowest point inside. Leave at 0 for capacity only.
Fresh water is 1000 kg/m3. Sea water is nearer 1025 kg/m3; use your product’s figure for anything else.

Worked out from Closed-form solid geometry: prism, cylinder, sphere, spherical cap and circular segment and 2 other sources.
Dimensions are taken as internal. Measuring outside the wall overstates the capacity by the wall thickness on every side.

How this is worked out

4 steps
  1. Shape: 0.9144 x 0.4572 x 0.4064 m.
  2. Capacity = 0.169901 m3 = 169.9 L = 44.88 US gal = 6 cu ft.
  3. No fill depth was given, so only the full capacity is reported.
  4. Full, the contents weigh 0.169901 m3 x 1000 kg/m3 = 169.9 kg (374.6 lb), before the weight of the tank, substrate or rock.
