In the world of agriculture and construction, calculating the length of an auger is crucial for efficient material handling. In this article, we’ll explore the workings of an Auger Length Calculator, discuss the formula used, and provide examples and applications. By the end of this post, you’ll have a solid understanding of the Auger Length Calculator and how it can help you in various projects.

What is an Auger Length Calculator?

An Auger Length Calculator is a tool that helps you determine the length of an auger needed for a specific bin or material handling system. It considers factors such as the bin diameter and eve height, enabling you to obtain an accurate measurement of the required auger length.

The Auger Length Formula

To calculate the auger length, the following formula is used:



  • AL is the Auger Length (ft)
  • E is the eve height of the bin (ft)
  • D is the bin diameter (ft)

Formula Breakdown

  1. Calculate half of the bin diameter (1/2 * D).
  2. Add the eve height (E) to the result from step 1.
  3. Multiply the result from step 2 by 1.4 to obtain the auger length (AL).

Example Calculation

Let’s work through an example using the formula:

Eve height of the bin (E) = 4 ft Bin diameter (D) = 3 ft

  1. Half of the bin diameter: 1/2 * 3 = 1.5 ft
  2. Add eve height: 4 + 1.5 = 5.5 ft
  3. Calculate auger length: 5.5 * 1.4 = 7.7 ft

Thus, the auger length is approximately 7.7 feet.

Applications of the Auger Length Calculator

The Auger Length Calculator is widely used in various industries, including agriculture and construction. Some common applications include:

  1. Grain handling and storage: Determining the correct auger length is essential for efficient grain movement and storage.
  2. Cement and concrete mixing: Accurate auger length calculations ensure proper material transport and mixing.
  3. Mining operations: Augers are used to transport materials such as coal, minerals, and ores, making correct length calculations vital for productivity.
  4. Environmental drilling: Auger length calculations are necessary for accurate drilling depth and sample retrieval.

Frequently Asked Questions (FAQs)

Why do we multiply the formula by 1.4?

We multiply the formula by 1.4 to account for the helical nature of the auger, which requires a longer length than a straight line from the bin’s eve to the outer edge.

Which units should I use for the Auger Length Calculator?

You should use feet as the unit of measurement for the formula provided, so ensure you convert all measurements to feet before performing calculations.

Can I use the Auger Length Calculator for different auger types?

Yes, you can use the calculator for various auger types, including grain, cement, and mining augers. However, you may need to consider specific industry requirements and safety factors.

What factors should I consider when selecting an auger?

When selecting an auger, you should consider factors such as the material being handled, required capacity, power source, and mobility, in addition to the correct length.


The Auger Length Calculator is a valuable tool for accurately determining the required length of an auger for various applications in agriculture, construction, mining, and more. By understanding and utilizing the Auger Length Formula, you can ensure the efficient handling and transport of materials, contributing to the overall success of your projects.
