Regarding units, in MSFS we have the options of Metric vs. the US System. This mostly works well, except many aircraft manage their fuel in Imperial Gallons rather than US Gallons. The volumes of the former is 20% great than the latter, so the difference is non-trivial!
Therefore, could Imperial Gallons (Imp Gal) be added to the options for units of measurement please.
Many thanks in advance.
Yes! We had a nightmare testing the Hunter and doing various conversions to get imperial measures. 
Is this perhaps on the Wishlist already?
Not that I could find. I did a search, plus the forum suggests similar topics when you create the title.
Do you know of such a wish on the list already?
No, I couldn’t find one either. I thought I had voted on one a few years ago, but clearly not. When working on older aircraft, all of the documentation is in the imperial system and its a nightmare trying to convert the various measures as some have a baring on others, and the nested calculations get very messy.
