Concrete Weight Calculator
How much concrete weighs — slab, cylinder or volume, wet and cured.
A wheelbarrow of concrete is ~150 kg; a 6 m³ truck, 14+ tonnes — check the site road. RC counts 2,500 kg/m³ in design because steel rides inside.
Formula
Concrete Weight Calculator is a free concrete weight for civil engineers, contractors and quantity surveyors — instant, accurate and 100% client-side, with the governing formula and reference shown next to the result so the number can be defended, not just quoted.
About Concrete Weight Calculator
How much concrete weighs — slab, cylinder or volume, wet and cured. The calculation implements W = V × ρ (2,400 kg/m³ ≈ 150 lb/ft³ normal-weight) (IS 875 Part 1 unit weights). A wheelbarrow of concrete is ~150 kg; a 6 m³ truck, 14+ tonnes — check the site road. RC counts 2,500 kg/m³ in design because steel rides inside.

Frequently asked questions
What formula does the Concrete Weight Calculator use?+
It computes W = V × ρ (2,400 kg/m³ ≈ 150 lb/ft³ normal-weight), per IS 875 Part 1 unit weights. The formula is displayed under the result.
What should I keep in mind when using this calculator?+
A wheelbarrow of concrete is ~150 kg; a 6 m³ truck, 14+ tonnes — check the site road. RC counts 2,500 kg/m³ in design because steel rides inside.
Does it include wastage?+
Yes — standard wastage/bulking factors are built in and stated in the formula line, so the quantity is an orderable number, not a bare geometric volume.
Is the Concrete Weight Calculator free to use?+
Yes — completely free, no sign-up, no limits. It runs client-side in your browser, so inputs stay private and results are instant even on slow connections.
