Mahogany Weight Calculator

Genuine mahogany (Swietenia species) has an average density of 35 pounds per cubic foot or 0.56 g/cm³. This can vary slightly between species, with African mahogany sometimes reaching 36-38 lb/ft³.

One board foot equals 144 cubic inches or 1/12 cubic foot. Multiply board feet by 0.0833 to get cubic feet, then multiply by 35 lb/ft³ to get weight. A single board foot of mahogany weighs approximately 2.92 pounds.

African mahogany (Khaya species) is slightly denser at 36-38 lb/ft³, while genuine American mahogany (Swietenia macrophylla) averages 35 lb/ft³. The difference is minimal for most practical purposes, usually just 1-2 pounds per board.

Mahogany is significantly lighter than oak. Red oak weighs about 47 lb/ft³ and white oak about 48 lb/ft³, making them roughly 35-37% heavier than mahogany for the same volume.

Yes, significantly. The standard 35 lb/ft³ assumes kiln-dried lumber at 6-8% moisture content. Green (freshly cut) mahogany can weigh 50-60% more due to water content, while fully air-dried wood at 12% moisture weighs about 10-15% more.
