The Grain Bin Capacity Calculator is an essential tool for farmers, grain handlers, and agricultural professionals who need to accurately determine the storage capacity of cylindrical grain bins. Whether you're planning harvest logistics, selling grain, or designing new storage facilities, knowing the precise capacity of your grain bins in both bushels and cubic feet is crucial for efficient farm management. This calculator uses the dimensions of your grain bin (diameter and height) to compute its maximum storage capacity, providing you with instant, accurate results that help optimize your grain storage operations.
Agricultural storage planning requires precision, and our calculator eliminates the guesswork by applying standard volumetric formulas to your specific bin dimensions. The tool is designed with simplicity in mind, allowing you to quickly determine storage capacity without complex calculations or specialized knowledge.
The capacity of a cylindrical grain bin is calculated using the standard volume formula for a cylinder:
Where:
Once the volume is calculated in cubic feet, it can be converted to bushels using the standard conversion factor:
This conversion factor (0.8 bushels per cubic foot) is the industry standard for most grains, though it can vary slightly depending on the specific grain type and moisture content.
For a grain bin with a diameter of 30 feet and a height of 24 feet:
This calculation provides the theoretical maximum capacity of the bin, assuming it's filled completely to the top with level grain.

The calculator provides two key measurements:
Volume in Cubic Feet: The total interior space of the bin, calculated using the cylinder volume formula.
Capacity in Bushels: The estimated grain storage capacity, calculated by multiplying the cubic feet by 0.8 (the standard conversion factor).
These calculations represent the theoretical maximum capacity of a cylindrical bin with level grain fill. In practice, actual storage capacity may vary due to factors such as:
Accurate bin capacity information helps farmers:
For those designing or expanding grain storage facilities:
When selling or buying grain:
For insurance and financial purposes:
For managing grain quality:
While our calculator provides a straightforward method for determining grain bin capacity, there are alternative approaches that may be useful in specific situations:
| Grain Type | Bushels per Cubic Foot | Standard Test Weight (lbs/bu) |
|---|---|---|
| Corn | 0.8000 | 56.0 |
| Wheat | 0.8030 | 60.0 |
| Soybeans | 0.7750 | 60.0 |
| Barley | 0.7190 | 48.0 |
| Oats | 0.6290 | 32.0 |
| Grain Sorghum | 0.7190 | 56.0 |
| Rye | 0.7140 | 56.0 |
| Sunflower Seeds | 0.5000 | 24.0 |
| Flaxseed | 0.7950 | 56.0 |
| Rice (rough) | 0.7140 | 45.0 |
To use these factors, simply replace the standard 0.8 multiplier with the appropriate value from this table when converting cubic feet to bushels for your specific grain type.
Cone Top Calculations: For bins with grain piled above the sidewall in a cone:
Moisture Adjustment: Some calculations factor in grain moisture content, as wetter grain takes up more space:
Displacement Calculations: For bins with center peaks, aeration tubes, or unloading equipment:
Direct Measurement: Some farmers use load cells or weight measurements during filling/emptying to determine actual bin capacity rather than theoretical calculations.
The need to measure and calculate grain storage capacity dates back to ancient civilizations. Early grain storage structures included underground pits, clay vessels, and stone silos, with capacity measured in primitive volume units.
In the United States, the development of standardized grain bins began in the early 20th century with the introduction of corrugated steel bins. These cylindrical structures became increasingly popular due to their durability, cost-effectiveness, and ease of construction.
The bushel, the standard unit for grain measurement in the US, has historical roots in England. The Winchester bushel, established in the 15th century, became the standard American bushel, defined as 2,150.42 cubic inches (approximately 35.24 liters).
The conversion factor of 0.8 bushels per cubic foot became standardized in the agricultural industry as grain bin manufacturing expanded in the mid-20th century. This factor represents an average value that works reasonably well across different grain types, though specific conversions can be used for greater precision.
Modern grain bin capacity calculation methods evolved alongside advancements in bin design. Today's calculations account for factors such as:
With the advent of digital technology, calculators like this one have made precise capacity calculations accessible to everyone in the agricultural sector, improving efficiency in grain handling and storage planning.
The calculator provides a theoretical maximum capacity based on the standard formula for cylindrical volume and the industry-standard conversion factor of 0.8 bushels per cubic foot. For most practical purposes, this calculation is sufficiently accurate, typically within 2-5% of actual capacity. Factors such as grain type, moisture content, and bin equipment can affect the actual storage capacity.
The standard calculation uses 0.8 bushels per cubic foot, which is generally accepted for corn and works reasonably well for most grains. For more precise calculations with specific grains, you can multiply the result by the appropriate factor for your grain type (e.g., wheat: 1.004, soybeans: 0.969, barley: 0.899, compared to corn).
For the most accurate results, measure the inside diameter of your bin. If you can only measure the outside, subtract twice the wall thickness (typically 2-3 inches for most bins). For bins with stiffeners or corrugations, measure from the inside peak of one corrugation to the inside peak of the opposite corrugation.
No, this calculator focuses on the cylindrical portion of the bin. For bins with cone tops, you would need to calculate that volume separately and add it to the result. Similarly, for hopper-bottom bins, you would need to subtract the volume that's not usable for storage.
Higher moisture content causes grain to swell, reducing the amount of grain that can be stored in a given volume. As a rule of thumb, for each percentage point increase in moisture content above the standard dry level, the storage capacity decreases by approximately 1.2%.
This calculator is specifically designed for cylindrical bins. For rectangular or irregular-shaped bins, you would need to use different formulas based on the specific geometry of those structures.
The calculator provides results in both cubic feet and bushels. If you need other units:
Storage capacity directly impacts farm profitability by providing flexibility in marketing decisions. With adequate storage, farmers can hold grain until market prices are favorable rather than selling immediately at harvest when prices are typically lower. Studies suggest that strategic grain storage can increase annual returns by 10-20% compared to selling all grain at harvest.
Rated capacity is the theoretical maximum volume of the bin, while usable capacity accounts for practical limitations such as unloading equipment, aeration systems, and the inability to completely fill or empty the bin. Usable capacity is typically 90-95% of the rated capacity.
