A price of 3.10 at a US pump and 2.65 at a New Zealand pump look close, but they aren't measuring the same thing. The US price is in US dollars per US gallon; the New Zealand one is in New Zealand dollars per litre. To compare them you need to fix two things at once: the volume and the currency.
The gallon adds its own trap. The US gallon (3.785 litres) is about 17% smaller than the imperial gallon (4.546 litres) once used in the UK, so "per gallon" figures from different countries can't be compared directly either. This converter handles all three units and over 30 currencies, and shows both prices side by side in whichever currency you choose.
UK and Irish pumps usually show pence or cents (for example 139.9p), so tick "Price is in cents / pence" to enter a pump price exactly as displayed.
A US gallon is 3.785 litres and a UK (imperial) gallon is 4.546 litres. That's about 20% more fuel in a UK gallon, so a "per gallon" price means different things depending on which gallon is used.
The United States prices fuel per US gallon, as do a few countries and territories that use US-style measures. The UK, Canada, Australia, New Zealand and almost everywhere else price fuel per litre, even if drivers still talk about miles per gallon.

Not quite. US pumps use the AKI octane scale while most other countries use RON. US regular (87 AKI) is roughly 91 RON, closer to a low-grade unleaded than Europe's standard 95. For a fair comparison, match grades rather than labels.
