Now, what about particulates in the flames? Whilst it would obviously depend on what is burning, Iâd imagine that a 10m column of flame from a gas release pipe on an oil rig would weigh less than a 10m column of flame from, say, a pine forest going up.o, since air (at sea level) weighs about 1.3 kg per cubic meter (1.3 grams per liter), fire weighs about 0.3 kg per cubic meter. One pound of ordinary fire, here on Earth near sea level, would take up a cube about 1.2 meters to a side.
