Concrete Weight Calculator

The Concrete Weight Calculator converts concrete volume to weight using material density. Select a concrete type such as Portland, reinforced, or gravel concrete, enter volume, and get weight in kilograms, pounds, and tons for ordering, hauling, or structural load checks.

Weight formula

Concrete weight is simply volume multiplied by density:

$$\text{Weight} = \text{Volume} \times \text{Density}$$

Standard Portland concrete has a density near 2300 kg/m³ (143.6 lb/ft³). Reinforced concrete is denser at about 2500 kg/m³ because of steel reinforcement. Always confirm density with your supplier for precast or specialty mixes.

Frequently Asked Questions

How much does a cubic yard of concrete weigh?

Standard Portland concrete weighs about 3,915 lb per cubic yard (2300 kg/m³). Reinforced concrete can reach about 4,214 lb per cubic yard.

How much does a cubic foot of concrete weigh?

At 150 lb/ft³, one cubic foot weighs 150 lb (68 kg). Asphalt concrete is lighter near 140 lb/ft³; reinforced mixes are heavier near 156 lb/ft³.

What density should I use for lightweight concrete?

Lightweight structural concrete often ranges from 70 to 120 lb/ft³ (1120 to 1920 kg/m³). Use the custom density option if your mix falls outside standard presets.

Why does concrete type change the weight?

Different aggregates, cement content, air entrainment, and reinforcement change density. Heavier aggregates and steel rebar increase total weight per unit volume.
