According to wikipedia, you tend to start with crude oil, then get both gasoline and diesel when refining the crude, so you can't trivially go from one to the other.
On average, U.S. petroleum refineries produce about 19 to 20 gallons of gasoline, 11 to 13 gallons of distillate fuel diesel fuel and 3 to 4 gallons of jet fuel from each 42 U.S. gallons (160 liters) barrel of crude oil. The product ratio depends upon the processing in an oil refinery and the crude oil assay.
This crisis implies that we've outsourced a lot of refining.
