Determining the Capacity of Your Salt Dome

First, calculate the storage volume of your salt dome:

Storage Volume = Length * Width * Wall Height

Next, account for the fact that your cone shaped pile of salt stores about 15% more volume above your bin blocks:

Storage Volume including overage = Storage Volume * 1.15

Next, multiply the volume by 72 lbs of salt per cubic foot of space:

Pounds of Salt = Storage Volume including overage * 72

Finally, convert pounds to tonnage:

Salt Dome Capacity = Pounds of Salt / 2000

Alternatively, you can use this simplified formula:

Salt Dome Capacity = Storage Volume of Salt Dome * 0.0414
