Alas, not in this case, since Google is interpreting that as a 42-gallon "petrochemical-industry traditional abstract measuring unit of crude oil" as opposed to a 55-gallon "physical container readers may have seen and everybody actually uses." (Including to hold crude oil, in the rare cases that it's not in an enormous tank or pipeline.)
Perhaps this is an example of where "intelligent assistant" software lands in a dangerous middle-zone of "wrong, but not wrong enough that it's obvious."
Anywho, if we reword it a bit and put in a less-rounded density, it comes out the same:
P.S.: The way it parses this small change is also amusing, where "in water barrels" isn't a change in the type of barrel, but instead introduces a non-SI unit of pressure, making everything murky indeed.
It is remarkable that you spotted the inaccuracy. You make a good point about it being wrong but not wrong enough.
OTOH, the correct answer by your reasoning is 44 barrels. For my purposes, 58 is right enough. I can't even visualize the difference between 44 and 58 barrels.
44 barrels is about 323 cubic feet (9.1 cubic meters). That's about the size of my bathroom.
57 tons in my tiny bathroom. Gallium is shockingly dense. Which makes sense.
(note I've slightly changed the prompt to match the "drums" OP used instead of barrels. This avoids the issue other child mentions of ambiguous units, as it clearly states the volume of drum it's using and gives options for others (e.g. the international 200L instead of the US 208L/55 GAL).
