See the attached picture. It is an Aero Products Research E6B Model 4. Notice the liters marks under imp. gal. and u.s. gal. How can I use the liters marks? Can I convert quantities to and from liters?
I reviewed the instructions manual. It is for a variety of E6B models and does not cover this small detail of having liters under imp. gal. or u.s. gal..
