Specific fuel consumption
This quantity is not dimensionless, so we need some units. From the size of it, 1.7 might be in lb/(lbf*h) but that is only a guess. Also need the metric equivalent e.g. kg/(N*s). Thrust to weight is dimensionless so no units is fine, though 1.31 is a bit away from 218/180=1.21.TSRL (talk) 07:29, 15 August 2011 (UTC)
