Construction
Concrete Volume Calculator
Estimate how many cubic metres of concrete to order for a rectangular slab, footing, or path. Multiply length × width × depth for the in-place volume — add a 5–10% waste allowance before placing the order.

Construction
Tile Quantity Calculator
Estimate how many tiles you need for a floor or wall, including a built-in 10% allowance for cuts and breakage. Multiply the floor area by the inverse tile area, round up, then add 10%.
