Petrol price and American gallons

 

The price of diesel has topped £1.50 a litre for the first time in Wigton. We've paid that once in a remote place in the very far north of Scotland. We wanted to know what it would have been in gallons, knowing the fuss that was made when petrol first went over £1 a gallon. I work on the idea that there are 8 pints in a gallon and that a litre is roughly 2 pints so 4 litres to a gallon. It's actually 4.546 litres to a gallon, meaning diesel is £6.91. The problem is that I've discovered that an American gallon is different.https://en.wikipedia.org/wiki/Gallon It looks as though we were running different sizes of gallon in the UK for measuring different things until the mid-1800s when it was standardised. We seem to have gone with the liquid gallon but the Americans went with the corn gallon. Anyway, there are 3.78 litres in an American gallon. Our American friends reckon to have reached about $3.50 max meaning 92.6 pence per litre.
