Yes - a cubic metre of wood is called a stere - derived from the French word stère, meaning "a cubic metre" - from which the French word stèrer also derives, meaning "to measure in cubic metres".
640 cubic feet
That depends on the type of wood and the size of the logs. A Stere of oak can weigh twice what a stere of pine does
128
About 50
It depends on the density of the wood as it can range from 170 to 1370 kg/cubic metre. At a total guess I would say less than 1 cubic feet.
A cord of wood is a unit of measurement for firewood equal to 128 cubic feet, typically stacked in a pile 4 feet wide, 4 feet high, and 8 feet long. A cubic meter of wood is a metric unit of measurement equal to the volume of a cube with sides measuring 1 meter in length (about 35.3 cubic feet). The main difference is in the volume each unit represents and the measurement system they belong to.
A cord of wood occupies a volume of 128 cubic feet.[1] Step 1: The volume of the room is:LxWxH = (8 yards)(8 yards)(5 yards) = 320 cubic yards------------------------------------------------------------------------------[2] Step 2: Converting that into feet where 3 feet = 1 yard, you get the following:(3 feet)^3 = (1 yard)^327 cubic feet = 1 cubic yard(320 cubic yards)(27 cubic feet / 1 cubic yard) = 8640 cubic feet.------------------------------------------------------------------------------[3] Step 3: Now you just divide:8640 cubic feet of space / 128 cubic feet of wood = 67.5 cords!!
Typically, one cubic foot of oak wood will produce about 24 million BTUs of energy when burned.
Wood has a wide range of densities.
a cord of wood is equal to 128 cubic feet of neatly stacked wood.
A stere is equal to a cubic meter and is used to measure wood in Europe. A cord, used in the United States, is 4' deep x4' tall x8' long of cut wood. There are 0.276 cords in a stere or, conversely, 3.625 steres in a cord. Most wood burning stoves now take 16" lengths of wood ("cordwood"), so it is common to buy wood for heating and cooking in units of 1/3 cords, 16"x4'x8'--16" being 1/3 of 4' (48").
