Concrete Weight Calculator

What it does

A free, easy-to-use tool that instantly calculates concrete weight based on volume and mix type - no sign-up required. Unlike generic calculators, it factors in different concrete densities (standard, reinforced, lightweight) for more accurate results. Built for contractors, DIYers, and roofers who need quick, reliable estimates for material planning, transport, and structural load calculations - all in one clean, mobile-friendly interface.

Use our Concrete Weight Calculator to get exact pounds, kg, and tons for standard, reinforced, and lightweight concrete.

Estimate the volume, weight, and cost of concrete for slabs, columns, or any custom volume. Numbers update as you type. Weight = volume × density of concrete. Normal concrete is about 2,400 kg/m³ (≈ 150 lb/ft³). Lightweight, aerated, and heavyweight mixes have different densities, which is why you can pick a type or enter your own. Cost = volume × unit price (converted to your chosen per-unit basis). For accurate quotes, ask your local supplier for the delivered price and add 5–10% waste to your order. Tip: Order at least 5–10% extra concrete to allow for spillage, uneven sub-grade, and slight over-pours. A standard cubic yard of concrete weighs 4,050 lbs (1,837 kg / 2.025 tons).
