Construction & DIY calculators
Construction and material calculations, supplier-ready.
Punch in your measurements and get back tons, cubic yards, bags, and boxes — the exact units your supplier quotes in — plus a cost estimate from the price you're paying. Every figure traces to a named source, so you can check the math before the truck arrives.
No sign-up. No app. Works on the phone in your truck.

Accuracy you can verify
- Supplier-ready unitsAnswers come back in tons, cubic yards, 50 lb bags, and full boxes — the way material is actually sold, so there's nothing to convert at the yard.
- Traceable numbersEvery density, yield, and coverage figure is tied to a named, checkable source. See exactly what a result is built on before you rely on it.
- Metric and imperialEnter feet, inches, meters, or centimeters in any field. The math handles the conversion and reports back in the units you order in.
Results are estimates — settling, waste, and site conditions vary — so confirm final quantities with your supplier before you place an order.
