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
Soil Bearing Capacity Calculator
Estimate the ultimate bearing capacity of soil beneath a square footing using Terzaghi's general bearing-capacity equation. Foundational geotechnical design input — used with appropriate safety factors to determine maximum allowable footing loads.
