How much wood is one hardwood ster?
One stere is a relative measure and corresponds to one cubic meter (1m wide, 1m high, 1m deep) of stacked logs with a length of 1m. Depending on the type of wood, this is 400 — 500 kg weight of dried wood. Depending on the length of the logs, the space requirement of the wood stack changes, as the spaces between them become smaller when they are re-stacked.
