Green wood will be substantially heavier due to its water content. Wood heavier than 1,000 kg/m3 will not float in water.

Note:

The weights given in these tables are necessarily approximate; variation within a class of substance can be large. I have taken an average weight per cubic metre for a given substance and rounded it to the nearest 25 kilograms. The exception is the Metals table, since there is seldom much variation in weight between different batches of the same metal I have given the weight per cubic metre reasonably accurately.

Weights in lbs/ft3 have been calculated at 1/16 kg/m3 and rounded out to the nearest pound, which should be accurate enough for roleplaying purposes.

Of course, the chances of ever having to calculate the weight of something like diamond in anything like cubic feet or metres are vanishingly small, but you just never know.........
