Every MeasureScout calculator is a simple formula you can check by hand. This page explains the conventions we use so you know what the numbers mean and where they can be off.
Units and conversions
- 1 cubic yard = 27 cubic feet.
- 1 square foot = 144 square inches.
- Depth entered in inches is divided by 12 to get feet before volume is worked out.
- Volume = length x width x depth, all in feet.
Waste and overage
Most materials need extra for cuts, spills and uneven ground. Each calculator lists the waste percentage it adds, and where there is a field for it you can change it. Defaults in the tools that add a fixed amount:
- Tile: 10% extra.
- Topsoil and fill dirt: 10% extra.
- Sod: 5% extra.
- Retaining wall blocks: 5% extra.
Rounding
Things you buy whole (tiles, sod rolls, blocks, gallons of paint, bags) are rounded up, never down. Volumes are shown to two decimal places.
Weight and density
Converting cubic yards to tons depends on the material and how wet and compacted it is. Where a calculator shows tons, it uses a stated figure (for example 1.1 tons per cubic yard in the topsoil tool as a default). Your supplier’s figure is the one to trust, so enter it when the tool allows.
Prices
MeasureScout does not publish prices. Where a tool shows a cost, it multiplies the quantity by the price you type in. Prices vary by region and season, so get a quote from a local supplier.
Worked examples
Each calculator shows its working under the result. Example numbers on our pages are examples, not recommendations.
Limits
Results are estimates. They assume simple shapes and level ground. Irregular areas, slopes, compaction and local building rules can change what you need. Check local codes and ask a professional before structural, drainage or electrical work.
