Mortar Tons to Cubic Yards Calculator

Convert a mortar tonnage into cubic yards to check coverage, capacity and storage.

Approximate volume

5.56 cu yd

High confidence

About 1.8 short tons per cubic yard for sand-cement mortar; close to concrete but without coarse aggregate. The inverse of the volume-to-weight figure. Allow extra storage space beyond the calculated volume for access and angle of repose.

Conversion factor applied
0.56 cu yd per short tons

Converting a mortar tonnage back to volume tells you how much wall it will build once the joint dimensions are known. Mortar has a working life that aggregates do not: once mixed it must be used before it stiffens, and retempering with extra water to extend it weakens the mix. That constraint means mortar is mixed in batches sized to the pace of laying, so the total tonnage matters less for delivery scheduling than for knowing how much sand and cement to have on site.

Add the equipment this sizes

This result is a specification — 5.556 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

How much wall will this build?
It depends entirely on joint thickness and unit size, so work back from the wall area and joint dimensions rather than from tonnage alone. Small units with thick joints consume far more per square foot.
Should I buy premixed or site-mixed?
Premixed gives consistency and suits small quantities; site mixing is cheaper at volume and lets the mix be adjusted. Consistency of colour across an elevation is a strong argument for premixed on visible work.
Why does mortar colour vary between batches?
Because sand colour, mix ratio and water content all vary between batches. On visible brickwork that shows as banding, which is why consistent batching and a single sand source matter.
