Introduction
Excavation Calculator — Excavation volume in m³ and cubic yards. Enter Length (m), Width (m), Depth (m) to get an instant, accurate result.
Formula
Volume = length × width × depth of the area to be dug, converted to cubic yards (× 1.30795).
Step-by-step
- Enter the Length (m).
- Enter the Width (m).
- Enter the Depth (m).
- Click Calculate to see your result instantly.
Real-world example
Example: With Length (m) = 5, Width (m) = 4, Depth (m) = 1, the Excavation Calculator gives Volume M3: 20, Volume Cubic Yards: 26.159.
Frequently Asked Questions
Does this account for soil swell after excavation?
No, this gives the in-place (bank) volume; excavated soil typically expands 15-30% in loose form when hauled or stockpiled.
How is excavation different from the Trench calculator?
They use the same length × width × depth formula — Excavation is meant for broader areas like basements, while Trench targets narrow linear digs like utility lines.
What inputs does the Excavation Calculator need?
You'll need to provide: Length (m), Width (m), Depth (m). All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.
How accurate is the Excavation Calculator?
The Excavation Calculator applies the formula exactly as calculated — Volume = length × width × depth of the area to be dug, converted to cubic yards (× 1.30795). — so results are precise for the inputs you provide. Accuracy depends on entering correct, realistic input values.
Is the Excavation Calculator free to use?
Yes, the Excavation Calculator is completely free, requires no signup, and runs instantly in your browser.
