Topsoil Tons to Cubic Yards Calculator

Convert a quoted topsoil tonnage into cubic yards to check it covers your area.

Approximate volume

8.33 cu yd

High confidence

About 1.2 short tons per cubic yard for screened topsoil at typical moisture; wet soil is appreciably heavier. The inverse of the volume-to-weight figure. Compare the resulting volume against your compacted or settled requirement, not the loose figure.

Conversion factor applied
0.83 cu yd per short tons

A tonnage quote for topsoil says little about whether the load will cover the beds, so converting to volume is the check that matters. Bear in mind that soil settles considerably: freshly spread topsoil loses a meaningful proportion of its loose depth within weeks as it consolidates and rain works it down. Ordering to the finished depth leaves borders sitting low by the second season. Add for settlement, spread slightly proud, and remember that a wet delivery buys fewer cubic yards per ton than the dry assumption predicts, because part of the weight on the ticket is water rather than soil.

Add the equipment this sizes

This result is a specification — 8.333 cu yd — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

Will this tonnage cover my beds?
Convert to volume, divide by the area, and that is the loose depth. Then allow for settlement — spread topsoil consolidates noticeably in the first weeks, so the finished depth is less than the spread depth.
Why did my soil delivery look small?
Usually because it was weighed wet and measured loose. Both effects run the same way: you get fewer usable cubic yards than a dry-density calculation suggests, and what you do get settles.
Can I compact topsoil to save volume?
You can, but you should not. Compacted topsoil drains poorly and roots struggle in it. Firm it lightly to remove air pockets and let rain do the rest.
