Calculate hole volume easily with our free online Hole Volume Calculator. Perfect for drilling, post holes, and concrete filling. Fast & accurate results!
Measuring the volume of a hole is essential for many construction and landscaping projects. Whether you're drilling a well, setting fence posts, or pouring concrete into a dug-out space, knowing how much material you need is crucial. That’s where our Hole Volume Calculator comes in making your work easier, faster, and more accurate.
Our online hole volume calculator helps you figure out how much space a hole takes up in just a few seconds. With both metric and imperial unit options, you can calculate the volume of circular, square, or rectangular holes in cubic meters, cubic feet, or liters.
A hole volume calculator is a tool that calculates the amount of space inside a dug hole. It helps determine the exact volume in cubic units (like cubic feet or cubic meters) so that you can fill it with concrete, soil, water, or other materials.
It’s especially useful for professionals in drilling, construction, and gardening. It’s also great for DIYers working on small landscaping or home improvement projects. Whether you are dealing with post holes or large foundation pits, this calculator ensures you know exactly how much material to use.
The calculation depends on the shape of the hole. Below are the most common formulas:
Formula:
Volume = π × (Diameter ÷ 2)² × Depth
Or
Volume = π × Radius² × Depth
Where:
This will give you the volume in cubic units (e.g., cubic feet or cubic meters).
Formula:
Volume = Length × Width × Depth
This is ideal for calculating the volume of holes with square or rectangular bases, often seen in foundation digging.
You can use this value to determine how much concrete or filling material you’ll need. This is particularly helpful if you’re working with post holes, concrete footings, or any drilled structure.
When it comes to measuring hole volume for drilling, post setting, or concrete work, precision matters. Our Hole Volume Calculator is designed to simplify the process and eliminate guesswork. Just plug in your values, select your shape and units, and you’ll get the exact volume needed for your project.
From square foot calculations to concrete estimation, this tool supports it all. It's ideal for construction pros, DIY enthusiasts, and anyone needing accurate hole volume data.
Use the formula for the hole’s shape. For a circular hole:
Volume = π × Radius² × Depth
Make sure all measurements are in feet to get the result in cubic feet.
Yes. The calculator helps you estimate how much concrete you’ll need to fill the hole based on its volume.
It supports feet, inches, meters, and centimeters. The output can be displayed in cubic feet, cubic meters, liters, or gallons.
Absolutely. It’s perfect for calculating the volume needed for post holes, especially when pouring concrete around fence or signposts.
Hollow volume is typically calculated by subtracting the volume of the inner object from the outer volume. For example:
Hollow Volume = Outer Volume - Inner Volume
Yes, you can enter values in metric units and receive results in cubic meters or liters.
