Spike's Calculators

Grain Volume in a Conical Pile - Metric

Calculate the number of Imperial and US bushels in a cone-shaped pile.
The calculation uses metres for measurements, and the volume results are in litres and cubic feet.

Grain Volume in a Conical Pile
V = 1/3HΠ(D/2)²
where V is the volume in cubic metres
H = the height
Π = 3.14159265
D = the diameter
one cubic metre (m³)  =  1000 litres (L)
one litre (L) = 0.0353146667214886 cubic feet (ft³)
one litre (L) = 0.027496156037386 bushels (bu) Imperial
one litre (L) = 0.0283775932584017 bushels (bu) US
