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.

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

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
hope this answers someones question

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

Re: convert 1 tonne of wood into cubic metres
I work for a company that writes software for logging companies. The conversion of tonnes to cubic metres is quite complex. As well as different species having different densities, you also have to consider the moisture content of wood. The higher the moisture content, the heavier the wood. Sometimes the moisture held in the wood can be 50% or more of the weight. This can vary depending on weather and how long the wood has been sitting around before being weighed.
Most companies do sampling to find out the moisture content and then run this measurement through standard tables that have a conversion for a certain species. Only then can the conversion between mass (kg & tonne are a measure of mass rather than weight) and volume be done.
