How this was calculated
Formula source(s)
- Inverse of approximately 1.1 short tons per cubic yard
- 1 short ton = 2,000 lb; a metric tonne is about 10% heavier
Inputs used
- Road Salt weight (short tons)
- 10
Intermediate steps
- Conversion factor applied
- 0.91 yd³ per short ton
Confidence note: About 1.1 short tons per cubic yard for rock salt; caking with moisture changes both density and handling. Road Salt heaps; allow room beyond this figure.
What this calculation does not cover
- Dividing this volume by the area to be treated returns a spread depth, and for salt that number means nothing. At the rates salt is spread the notional layer works out at tens of microns — scattered grains on a wet surface, not a course of anything. Depth arithmetic that works for gravel or sand does not carry across.
- The tonnage in the bay is not the tonnage that reaches the road. Spinners throw salt past the treated width, traffic and drainage move more of it into the gutter and the verge, and lumps broken out of a caked face pass through a spreader without metering evenly. A stock planned as though the whole load lands where it is aimed runs short.
- Size the bay on the load as tipped, not on what the heap becomes. Salt consolidates as it takes up moisture and cakes, so a heap that has stood takes less room than it did on delivery — but that is not capacity you can use, because a fresh load tipped against a caked face piles on top rather than filling in. How fast it happens depends on heap height, cover and humidity, so there is no interval to plan around.

Converting a salt tonnage into volume tells you the storage space required, which is the practical constraint for most operations. Application rates are specified by weight per unit area, so the tonnage figure is what determines how many treatments a stock provides. Over-application is both wasteful and environmentally damaging, since excess salt runs off into soil and watercourses, and it accelerates corrosion of vehicles and reinforced concrete alike.
