🏚️ Silo Capacity Calculator — Grain Storage Tonnes
Calculate grain storage capacity in tonnes for round and square silos. Plan harvest logistics and storage requirements.
Quick answer: 6m dia × 10m high = 212 tonnes wheat. 9m × 12m = 570 tonnes. 12m × 15m = 1,275 tonnes. Bulk density: wheat 0.75 t/m³, barley 0.68 t/m³, canola 0.68 t/m³.

Storage Capacity (tonnes)
📐 How Silo Capacity Is Calculated
Round: Volume = π × r² × height. Tonnes = Volume × Bulk density.
Square: Volume = length × width × height. Tonnes = Volume × Bulk density.
📊 Worked Example
6m diameter, 10m high round silo. Wheat bulk density 0.78 t/m³.
Radius = 3m. Volume = 3.14 × 9 × 10 = 283 m³
Tonnes = 283 × 0.78 = 221 tonnes wheat
❓ Frequently Asked Questions
Round silo: Volume = π × r² × height. Tonnes = Volume × Bulk density. Example: 6m dia × 10m high = 283 m³ × 0.75 = 212 tonnes wheat.
Wheat: 0.75-0.80, Barley: 0.65-0.70, Canola: 0.65-0.70, Oats: 0.50-0.55, Corn: 0.70-0.75 t/m³.
6m × 10m: Wheat 212t, Barley 185t, Canola 185t, Oats 150t. 9m × 12m: 570t wheat. 12m × 15m: 1,275t wheat.
Total tonnes ÷ silo capacity = number of silos. Add 20% buffer. Example: 1,000t ÷ 200t = 5 + 1 spare = 6 silos.
