Use this construction calculation for preliminary quantity, geometry, material, load, or coverage planning when dimensions and units have been measured consistently.

Loose volume (m³)

Required number input.

Compacted-to-loose ratio

Required number input.

Convert loose soil volume to compacted volume using a measured compacted-to-loose volume ratio. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Compacted volume (m³)

The resulting compacted volume returned as a number.

• Earthwork volumes depend on survey surfaces, soil variability, swell and shrink factors, compaction target, groundwater, side slopes, haul conditions, and temporary works. Geotechnical and site-safety requirements remain separate.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify dimensions on site, use current product data and local code requirements, include an explicit waste or safety allowance where appropriate, and obtain qualified structural, electrical, plumbing, or geotechnical review when required.

• Swell Factor Volume

  Convert in-place excavated volume to loose volume with a specified swell percentage.

• Circuit Load Amps

  Convert electrical load power to current for a DC circuit or AC load with unity power factor; does not size a breaker.

• Concrete Volume

  Calculate rectangular concrete volume in cubic meters from length, width, and pour thickness measured in meters.
