Marking my sight glasses: Barrels or Gallons

[UnFermentable]

Is it best to mark my tank site gauges in gallons or barrels? I do have flow meters and I marked everything in barrels. But now, I'm wishing I had marked them in gallons.

I think many might argue for hL (hectoliters), and the metric system in general for ease of measurements.

For me, at a certain point it stopped making much difference. I think of gallons in terms of growlers/kegs most of the time, so it is easy enough for me to quantify gallons into barrels and vice versa. Same with the metric system. 2 liter growlers are just a hair over a half gallon growler at the conversion rate of 3.785 liters per gallon, or 1.17 hL per bbl. 30 & 50 liter kegs for foreign operations.

It is really about using the unit of measure that is most convenient for your purposes, and that you can translate most fluently.
