The grain bin calculator works out total grain weight, grain volume in bushels and volume of grain from diameter, grain weight, sidewall height, roof height, hopper height, length, width, one way, grain volume in bushels, grain volume in bushels, grain volume in bushels and grain volume in bushels. Enter what you have and the relationship is applied straight away, so you get the answer without working through the algebra yourself.
What Is the Grain Bin Calculator?
The grain bin calculator works out total grain weight, grain volume in bushels and volume of grain from diameter, grain weight, sidewall height, roof height, hopper height, length, width, one way, grain volume in bushels, grain volume in bushels, grain volume in bushels and grain volume in bushels.
Biological relationships are usually approximations rather than exact laws, so the output is best treated as an estimate with a sensible range around it.
How the Grain Bin Calculation Works
The calculation applies the relationship as published, step by step, so each intermediate value can be checked against the underlying theory.
Keep the units consistent throughout. Mixing a percentage with a proportion is the single most common source of an answer that is out by a factor of a hundred.
Assumptions Worth Knowing
Any relationship used here assumes a constant rate, a representative sample, or a stable population. Real populations rarely meet those conditions for long, so treat the answer as a guide.
Where the inputs are field measurements, a single misread value can shift the result noticeably. Measure carefully and record what you used.
A Worked Example
Working through an example, with diameter set to 10, grain weight set to 5, sidewall height set to 2, the calculator returns radius of 5, and volume of grain of 20, and grain volume in bushels of 15.572. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out total grain weight?
Enter diameter, grain weight, sidewall height, roof height, hopper height, length, width, one way, grain volume in bushels, grain volume in bushels, grain volume in bushels and grain volume in bushels. The calculator then works through the relationship and reports total grain weight, grain volume in bushels and volume of grain.
What does the grain bin actually calculate?
It takes diameter, grain weight, sidewall height, roof height, hopper height, length, width, one way, grain volume in bushels, grain volume in bushels, grain volume in bushels and grain volume in bushels and converts them into total grain weight, grain volume in bushels and volume of grain using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter diameter?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
