Solid cubic metre

The amount of wood is reported differently in different situations. Solid cubic metre is used in statistics and in wood trading. Solid cubic metre means full load of wood matter. One solid cubic metre is 1 000 litres in liquid.

Stacked cubic metre

Stacked cubic metre is tightly stacked, 1m x 1m x 1m sized unit. It is usually used with wood chips.

Loose cubic metre

Chips and logs are usually sold in loose cubic metres. As the name suggests, in this case the wood is stacked loosely.
