slab 體積 1.2 m³；重量 2880 kg。
At a glance:Slab V = length × width × thickness; cylinder V = π·(D/2)²·height. Weight = V × 2400 kg/m³. Complements cement-mix and rebar calculators.
Formula
slab: V = L·W·T.
cylinder: V = π·(D/2)²·H.
weight = V × 2400.
How to Use
- Select a shape and fill in the dimensions.
- The tool returns volume (m³) and weight (kg).
Case Studies

V = 1.2 m³; weight 2880 kg.
FAQ
What density is used?
Ordinary concrete is about 2400 kg/m³; special mixes vary.
How does this differ from cement-mix?
cement-mix computes the mixing ratio; this computes volume.
What precision?
Volume to 3 decimals, weight as integer.
