“In US dollars per UK gallon, what is the cost of petrol in the UK on average?”

As of May 2026, the average cost of petrol in the United Kingdom is approximately $7.50 to $8.00 USD per UK (Imperial) gallon. This estimate is derived from recent data indicating petrol prices around £1.50 to £1.60 per litre. Using the conversion factors of 4.546 litres per UK gallon and an approximate exchange rate of 1.27 USD to 1 GBP, the calculation is as follows:

Price per litre: ~£1.50–£1.60 litres per UK Gallon: 4.546 Price per UK Gallon (GBP): ~£6.82–£7.27

Price per UK Gallon (USD): ~$8.66–$9.23 Note: Earlier 2026 data from April 2026 cited a price of £1.57 per litre (approx. $2.12 USD per litre), which converts to roughly $9.65 USD per UK gallon.

Prices fluctuate daily based on global oil markets and exchange rates. A common rule of thumb cited by users is that UK petrol costs roughly 2.5 times the price of US gasoline when converted to US gallons, but using UK gallons reduces this multiplier to approximately 1.3–1.5 times the US price.

“What’s the equivalent cost in Germany?”

As of April 2026, the average cost of petrol in Germany is approximately $9.48 USD per UK gallon. This is based on an average price of €2.14 per litre, as reported by the European Commission for late April 2026. Using the conversion of 4.546 litres per UK (Imperial) gallon, this equates to roughly €9.73 per UK gallon. Converting this to US dollars using a representative exchange rate yields the $9.48 figure.

This makes the average cost of petrol in Germany slightly higher than the average cost in the United Kingdom during the same period.
