Description
Cubic yards for a slab, footing or column, waste included and rounded to the quarter yard plants actually sell. Works offline. How much concrete, answered in the time it takes to open a tab. Pick a shape, type the dimensions, read the number. The popup gives you the amount to order: volume plus a ten percent waste allowance, rounded up to the quarter yard that ready mix plants actually sell in. Three shapes: slab or pad, footing, and column. Measure however you already measure. Feet and inches, inches, yards and inches, meters and centimeters, or centimeters. Switching converts your numbers rather than reinterpreting them, so nothing drifts. When you need more than the volume, one click opens the same pour on concrete-calculators.com with your measurements already filled in, where you get the cost breakdown, bag counts, gravel, reinforcement and labor. No account, no permissions, no tracking. The extension asks for no browser access at all and makes no network requests. The math runs locally, so it works with no connection. Estimates are for planning. Confirm quantities and mix specs with your supplier and local building department before you order.
