* Typical grain densities: Wheat approximately 800 kg/m3 (50 lb/ft3); Corn approximately 720 kg/m3 (45 lb/ft3); Rice approximately 580 kg/m3 (36 lb/ft3). Capacities based on bin filled to eave with grain peaked in roof area at 28° slope. Bushels based on 1.25 cu. ft./bu. Metric ton calculations assume wheat at 800 kb/cubic meter; corn at 720 kg/cubic meter; and rice at 580 kg/cubic meter. All maximum capacities include a 6% compaction allowance as determined by the American Society of Agricultural Engineers (ASAE) standard S413.
