Calculates the volume and quantity of lumber boards for construction.

What is it?

The timber volume calculator works out the cubic volume and weight of boards or beams from the quantity, length and cross-section.

Formula

Volume (m³) = quantity × length × width × thickness Weight (kg) = volume × density (500 kg/m³ for pine)

Example

50 boards of 6 × 0.15 × 0.05 m (150 × 50 section). Volume: 50 × 6 × 0.15 × 0.05 = 2.25 m³. Weight: 2.25 × 500 = 1,125 kg.
