It appears that a British Gallon is different from a US gallon. This derives from the fact that where a US pint is 16 fluid ounces, a British pint consists of 20 fluid ounces. There are still 8 pints in a gallon. There are (approximately) 28.8ml in a fluid ounce. There are 160 fluid ounces in a British gallon. There are 128 fluid ounces in a US gallon. Therefore, there are (approximately) 4.6 litres in a British gallon; and (approximately) 3.7 liters (sic) in a US gallon.
