Well 1 t = 1000 kg. Just divide by the density.

Unfortunately the density of wood varies all over the place from 170 kg/m³ for balsa to 1320 kg/m³ for lignum vitae. Even common firewoods vary from about 500 - 1000 kg/m³. So you have between 1 and 2 m³ of firewood probably, possibly wider variation with "odd" species.

See the link for density by species. Unless you know what you have, you can't make an accurate estimate.

You are totally wrong John ! one tonne wood is not about the weight, its about the volume. One tonne wood equals too 7200 inch3.

You are thinking of cubic meter, lol.

With metric, the differentiation between weight and volume is quite strict. Tonne is weight, cubic meter is volume.

I'm not sure what he is thinking as a cubic meter is 61023.74 in³

"Wood people" have told me to use 35 pounds/cu. ft. as a default value for the density of wood used in construction.

I think it is a wind-up. There seems to be a spate of threads from the dark ages that are being pulled up with some smart comment on them.

Re: convert 1 tonne of wood into cubic metres

i been trying to figure this out for the longest time and as best as i can explain

im trying to buy teak and instead of charging by the volume or m3 they price by tonne?? cannot be ton as 1 ton as spelled equals 1000kg

they calculate tonne as follows height (in inches) x width (in inches) x lenght (in feet)

strange right?

i was quoted price for 1 tonne of grade a teak at 21500 ringgit malaysia

i asked for 1 block of teak 6in high x 12 wide x 8 ft long, his calculation came out to o.o8 tonne using 6x12x8/7200

price was 1720

i went to 3 lumber yards and they all calculated this way.

how u can mix inches and feet and come up with a value beats me.

anyhow, using above size i can calculate volune in cubic feet or even m3 and work backwards to get what is m3 price for my wood

i wonder if the 7200 constant is for all wood or teak only? wonder if this 7200 was derived from specific gravity of teak somehow

lots of question still but now i know how to calculate tonne pricing for teak

Tonne is the common spelling in the rest of the world for what the US calls a "metric ton," 1000 kg. The density of teak ranges from 630- 720 kg/m³ according to one website. I don't doubt the ability of an unscrupulous seller to rename and misuse a unit, but a tonne is 1000 kg.

Here are a couple of sources showing price per cubic meter (metre):
