FAQ
How is tank capacity calculated?
Rectangular = width × depth × height; cylindrical = π × radius² × height, giving volume in ㎥. One ㎥ is 1,000 liters and water weighs about 1 tonne per ㎥.
How do liters and tons relate?
1 ㎥ = 1,000 L. Since water density is about 1,000 kg/㎥, one ㎥ of water weighs about 1 tonne (1,000 kg).
Is usable volume different?
Yes. With freeboard or an overflow, the actual stored volume is less than the geometric capacity. Enter the effective water height for the usable volume.
