Contradictory numbers in Energy Content table This isn t my field of expertise but I noticed what seem to be some contradictory numbers or bad conversions in the Energy Content table For example Aviation Gasoline is shown as having a lower number of MJ liter and BTU gallon than Regular Gasoline which doesn t sound right But when converted to MJ kg the number is higher than gasoline I have another remark regarding the Energy content section Is the displayed energy content the true energy content or the energy content when used in a conventional internal combustion engine this would change the figurs greatly as eg gasoline is burnt here with 20 efficiency while hydrogen is burnt with 40 60 efficiency
