About NOK 9.5 per liter
1 USD = 5.98 NOK
1 Gallon = 3.78 Liters
So (And please check my math) working out the math, we come out to
9.5 NOK per liter X 3.78 liters per gallon = 35.91 NOK per US Gallon
35.91 NOK divided by 5.98 NOK per USD = $6.00 per gallon...
Bad, but not quite as horrible as I was expecting, to be honest...
