If you're talking about prices in guilders, as the others have said, just take the price, divide in half and add 10%. No need to worry about the conversion to liters, etc., as everywhere in SXM is priced in liters regardless. And the price on SXM is going to be WAY more than in the US. Frankly, other than the scam some gas stations were running, with the pump showing guilders and them asking you to pay that price in DOLLARS, I don't worry about the price of gas on SXM. We generally fill up once on island. Not worth even worrying about the price of gas at one station versus another or on French versus Dutch side.
