Use this workshop calculation to turn measured dimensions and the selected construction convention into a cut, spacing, fit, or material-planning value.

Raw density (kg/m³)

Raw density in kilograms per cubic metre, between 100 and 1400.

Length (mm)

Length of the workpiece in millimetres.

Width (mm)

Width of the workpiece in millimetres.

Thickness (mm)

Thickness of the workpiece in millimetres.

Compute workpiece weight in kilograms from raw wood density and millimetre dimensions. 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]

Weight (kg)

Weight of the rectangular workpiece in kilograms.

• Nominal dimensions, kerf, moisture movement, hardware clearances, wall squareness, and manufacturer instructions can change the required shop dimension. Measure the actual assembly and test critical joints on scrap before cutting finished material.
• 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.

Complement the calculated dimension with a physical story stick, dry fit, or full-size layout. Follow the hardware, coating, adhesive, or machine manufacturer's limits where they differ from a rule of thumb.

• Particle Board Density Lookup

  Classify a particle board by thickness and return its nominal raw density in kilograms per cubic meter.

• Holz Rohdichte

  Bulk density of wood at a specified moisture state from mass and volume measured at that same state.

• Holz Darrdichte

  Oven-dry wood density from oven-dry mass and oven-dry volume; both measurements must be made after drying.
