About Green Weight Calculator

Freshly cut (green) timber can hold more weight in water than in wood fiber - some species are over 100% MC, meaning water weighs more than the dry wood itself. Knowing accurate green and dried weights is essential for transport safety, crane and forklift capacity, container loading limits, and freight cost estimation.

Formulas Used

Oven-dry mass = Volume x Basic DensityWeight at MC% = Oven-dry mass x (1 + MC/100)Green weight = Oven-dry mass x (1 + Green_MC/100)Water to remove = Weight_current - Weight_targetBasic density = oven-dry mass / green volume (kg/m3)

Frequently Asked Questions

Why is green timber so much heavier than dried?

Green wood can carry 40-200% moisture content. At 100% MC, the water weighs as much as the dry wood, so the board is twice its dry weight. Drying to 12% removes most of this - a 1m3 green hardwood log can lose 300-500 kg of water.

How many cubic metres fit in a 20ft container by weight?

A 20ft container has a ~28 tonne payload limit. Green dense hardwood (1000+ kg/m3 at green MC) maxes out at ~20-25 m3 by weight before volume. Dried timber at 12% lets you load more by weight. Use this tool to check before booking.

What is basic density vs density at 12%?

Basic density uses oven-dry mass divided by green (swollen) volume - a stable reference for weight calculations. Density at 12% MC is higher because it uses the shrunken dry volume and includes 12% water. This tool uses basic density for accurate moisture-based weight estimates.
