What is a Gallon?
Imperial Gallons as seen in UK , Canada, or Cayman islands (etc...) below are larger. Use this conversion page.
We use USA Miles per gallon Gallons! (and oddly USA Gallons are at "Imperial miles" , no laughing now, at the Gringo's funny ways) Miles(imperial) per USA Gallon. No joking matter that.....
USA Imperial Miles per USA gallon. (funny , huh?) or M[imp]PG[US]. or MPG for short.
Confusing yes, but this nice can, shows the truth. See M[imp]PG[imp] below.
This photo is for those rare Canada folks still using Imperial Gallons. (sold, at rare gas station pumps) Right photo at Cayman Islands, CI.
If the above can was, 1 Imp. Gallon, the U.S. mark would be 1.2 Gallons. see?
