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
Excavation Volume Calculator
Calculate the volume of earth to be removed for a rectangular excavation — foundation pit, trench, or basement cut. Output is the in-situ (bank) volume in cubic metres, used for haulage planning, disposal cost estimation, and equipment sizing.
