How the calculator works

  • Rectangular volume = width × depth × height × quantity
  • Square volume = side² × height × quantity
  • Circular volume = π × (diameter/2)² × height × quantity
  • Optional rebar displacement per row = bars × π × (bar_diameter/2)² × height × quantity (subtracted from gross concrete volume)
  • All dimensions are converted to meters before volume is calculated. Totals are shown in m³, ft³, and yd³.

Always verify against drawings, local codes, cover requirements, and site instructions.
