aircraft fuel consumption question

[Newark777]

Now I have a question along these lines…
Flying the 737-400 (in MS Flight Simulator), the engine stack on the instrument panel has “FF/FU” which I assume has something to do with fuel flow. It ranges from about 0.7 at idle to 11.5 at full-throttle.

What is this unit of measure? 11.5 what per what? 11,500 lbs/hr?

I typically cruise at about 3.9 to 4.1. A few mor points and I will overspeed. So if my calculations above are correct, then this really doesn’t make sense as I would be cruising at 4,100 lbs/hr, but my calculation for the -800 is 6,444 lbs/hr.

…or is THIS as real as it gets?

Hopefully you know already that not much in MSFS is very accurate, especially the stock aircraft.
