Work out grain storage capacity instantly with clear inputs, formula shown and shareable results.
Bulk storage capacity is simply volume x bulk density. Wheat runs about 780 kg/m3, maize 720, paddy 575 and soybean 750, so the same building holds very different tonnages depending on the commodity. Floor loading matters too — three metres of wheat puts about 2.3 tonnes on every square metre.
Storage capacity
Capacity (t) = length x width x grain depth x bulk density / 1000
Grain exerts substantial lateral pressure on walls and entrapment in flowing grain is fatal. Have storage structures designed and certified by an engineer and never enter a bin without lock-out and a harness.
No. Stacked bags waste 25-35% of the volume in voids and aisles, so a building holds substantially less in bags than in bulk.
Check the wall design. Grain exerts lateral pressure that rises with depth, and flat-store walls not designed for grain loading can fail. Bulk depth over about 3 m needs an engineered structure.
