Sand & Aggregate Calculators
Free, practical tools for sand and aggregate planning — estimate sand volume, convert between volume and weight, size paver bedding and sandbox fills, work out a concrete mix, and scope a sand filter.
🏖️ 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
