SANDRATE
Sand, aggregates, and the calculators every builder and landscaper needs.
From estimating sand volume and converting between volume and weight to sizing paver bedding, filling a sandbox, working out a concrete mix, and scoping a sand filter, SandRate pairs free hands-on sand and aggregate calculators with practical guides and a richly illustrated museum. Build smarter, waste less.
Sand & Aggregate Calculators
Free tools for sand and aggregate planning — sand volume calculator, sand weight converter, paver sand calculator, sandbox sand calculator, concrete mix calculator, and sand filter calculator.
🏖️ Sand Volume Calculator
Estimate how much sand you need to fill an area from its length, width, and depth — in cubic feet, cubic yards, and cubic metres, plus a weight in US tons and metric tonnes
⏳ Sand Weight Converter
Convert sand between volume and weight — cubic feet, yards, and metres to pounds, kilograms, US tons, and tonnes — for dry or wet sand using typical densities
🧱 Paver Sand Calculator
Work out the bedding sand needed under a paver patio, walkway, or driveway from the paved area and bedding depth — in cubic feet, cubic yards, US tons, and 50-lb bags
🪣 Sandbox Sand Calculator
Calculate how much play sand fills a rectangular or round sandbox from its dimensions and fill depth — in cubic feet, pounds, and the number of 50-lb bags to buy
🏗️ Concrete Mix Calculator
Break a concrete volume into cement, sand, and aggregate by mix ratio, applying the 1.54 dry-volume factor and converting cement into 50-kg bags, with sand and aggregate in tonnes
💧 Sand Filter Calculator
Size a rapid sand filter from a design flow rate and filtration rate — the required bed area, the minimum tank diameter, and the backwash flow your pump must supply
Sand & Aggregates Museum
Dig into an immersive museum of sand & aggregates — the grains from silica and quartz to gravels, the concrete, glass, and abrasives sand builds, the dunes, deserts, and sandstone it forms, and the sandcastles, art, and hourglasses it fills, each in its own gallery, so you can get to know the story behind every grain: what it is, how it is used, and the part it plays in building and shaping our world.
