Civil
Steel Weight Calculator
Calculate the total weight of steel reinforcement bars (rebar) given their diameter, length, and quantity. Standard quantity-take-off tool for reinforced concrete, using the well-known d²/162 formula derived from steel's density.

Civil
Concrete Volume Calculator
Estimate the in-place concrete volume for slabs, footings, walls, and other rectangular structural elements using V = L × W × T. The geometric volume in cubic metres — add 5–10% waste before placing the order.
