Cubic meter of wood in kg

The unit of measurement, cubic meter, is only used in connection with wood. As more wood is used for heating, it is becoming more important again. But how many kg of wood are there in one cubic meter?

Firewood is in great demand again.

A cubic meter

  • The cubic meter is an outdated unit of measurement for the volume of wood and is often referred to as the ster. It is mainly used for the firewood billing by the forester or forest owner.
  • From February 1970, only the liter and the cubic meter are officially permitted as volume units in Germany. That is why the cubic meter is also called a stacking volume (VSt.) designated.
  • The volume of a body is determined by measuring the length, height and depth of the object and then multiplying it. The same goes for a pile of wood.
  • Such a pile of wood is not only made of wood. Depending on how straight the pieces are and how neatly they were stacked, such a stack also contains gaps, spaces of air. A neatly packed pile of wood with gaps one meter long, one meter high and one meter deep is one cubic meter of wood.
  • In contrast to this, there is also the solid cubic meter and the loose cubic meter. The solid cubic meter corresponds, like the cubic meter, to a pile of wood one meter long. The gaps are not included here. The bulk cubic meter is a loosely tipped pile of wood with the dimensions 1 m x 1 m x 1 m. The gaps are particularly large here.

Wood in kg

  • You always get the weight of the wood in kg via a scale. The cubic meter is a volume measure and is expressed in m3 specified. The weight of an object depends on several things. On the one hand on the density, on the distance to the surface of the earth and especially in the case of wood, on the drying state. Green, i.e. fresh wood is more humid and therefore heavier than dry, seasoned wood. Wood that has been in the rain for a long time also weighs a few kg more.
  • In the forest, it is much easier to measure the length, width and height of a pile of wood than it is to weigh it. To do this, the wood would either have to be transported to a scale or a scale would have to be transported to the wood via impassable forest paths. That would be a considerable additional effort and the cost of the wood would increase.
  • For this reason, the volume of (firewood) on the forester's account is given in cubic meters and not the weight in kg. For this reason there is no conversion factor from cubic meters to kg. It always depends on the nature of the wood.
