All U. S. gasoline pumps are now designed to quickly be converted to liter.
All oil bottles under 5 quarts are 1 liter, but containing 946 mL for U. S. consumption. For a short time, AutoZone sold 5 Liter jugs in Texas. While a professional tourist, I saw 1 Liter labels in MT, UT, IA and WY.
Since 2000, all vehicles sold in the U. S. have digital odometers easily converted to read kilometers by a dealer.
Since 1992, all U. S. consumer products must carry customary and metric measure.
Proctor and Gamble has asked Congress for permission for voluntary metric only consumer labels. P & G wants to eliminate (4.2 fl. oz.) on their 125 mL Old Spice After Shave so they can use the same label in the U. S., Australia and New Zealand. New Zealand does not permit English measure on consumer products. The House has had no time for P & G. Far too busy investigating Trump.
I'm not in the oil and gas business but I've certainly logged plenty of time around refineries and car makers.
