• 1 ft 3 = 0.02832 m 3 = 28.32 dm 3 = 0.03704 yd 3
• 1 ft (foot) = 0.3048 m = 12 in = 0.3333 yd

### Mass of a Pile

The mass of a pile can be calculated as

m = ρ V                              (1)

where

m = mass (kg, lb)

ρ = density of the volume in the pile (kg/m 3 , lb/ft 3 )

V = stockpiled volume (m 3 , ft 3 )

For density - be aware of the bulking factor for the stockpiled material.

### Example - Stockpiled Anthracite Coal

Anthracite coal with density 65 lb/ft 3 is stockpiled in a conical pile with diameter 30 ft and height 8 ft .

According the diagram above the volume of the pile is approximately 2000 ft 3 .

The total mass of the pile can be calculated as

w = (65 lb/ft 3 ) (2000 ft 3 )

= 130000 lb
