Converting cost of gasoline from liters to gallons.

     Gasoline is sold in Thailand by the liter and the prices posted are in how many baht per liter.  It sometimes is difficult for those who use gallons to determine how much they are paying to use their vehicles.  You can use the formulas below to help get a clearer idea of what you are paying while thinking in gallons and your home currency.

For British Gallons

(Baht per liter * 4.54)/exchange  rate

For US Gallons

(Baht per liter * 3.785)/exchange rate

Example:  say gasoline is 26.5 baht per liter and the exchange rate for dollars is 34.5 and for the pound is 64.98.

Gasoline will cost you:

British:  (26.5 * 3.546)/64.98 = £1.45 per British gallon

US: (26.5 * 3.785)/34.5 = $2.90 per US gallon

Miles Per Gallon

Many who keep to a tight budget (and are a bit anal) often like to keep track of how far their vehicle can go on a certain amount of gasoline.   You can use the formula below if you still can’t think in liters and kilos.

(kilometers traveled / 1.6) / (liters used /3.785)  

or 4.54 for British gallons.

Example:  You traveled 250 kilometers using 20 liters

(250/1.6) / (20 / 3.785) = 29.57 miles per gallon
