Is there an easy way to tell the current range of a ship given its current fuel reserves? I see that there's a 'range' box under the maintenance heading of the individual units window, but its not making much sense to me. As an example, I have two ships of the same class with 190k litres of fuel for 168bkm range. Ship A has 157,261 litres of fuel for 2651.5b range. Ship B has 141,313 litres of fuel for 2301.7b range. The ratios seem to be the same between range and fuel but what exactly does the b mean? Why isn't range listed simply in bkm?
