The factors we log scalers use in British Columbia are: For tightly-stacked gymnosperm cordwood, 1 cord = 2.3 cubic metres solid volume. Tightly-stacked rounds with bark ("average" bark?) = .65 of solid volume (xylem) Chemical composition and density can vary greatly by site conditions, age, and where on the stem the wood grew. Larch butts, for example, can be up 23% (by weight) arabinogalactan. One board can be as light as pine and the next would have been a "sinker" log, if logs were still transported by boom or river drive. Best to do measurements on some trial batches from a source as typical as you can get to real life.
