Construction
Rebar Weight Calculator
Estimate the weight of steel reinforcement bar (rebar) from its size and total length for material ordering and crane-load planning. Useful for concrete contractors, structural engineers, and quantity surveyors.

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.
