I-19 from Tucson, AZ to Nogales in Mexico has distances posted in kph, so you can choose to drive on that freeway to tell you how many km away the exit is.
You may not be able to buy gas in liters instead of gallons, but you may be able to sell them in liters if you own a gas station and are willing to purchase the equipment and make that choice.
Interstate 19 is unique among US Interstates, because signed distances are given in meters (hundreds or thousands as distance-to-exit indications) or kilometers (as distance-to-destination indications), and not miles. However, the speed limit signs give speeds in miles per hour. According to the Arizona Department of Transportation (ADOT), metric signs were originally placed because of the push toward the metric system in the United States at the time of the original construction of the highway.
Its not the only one. Highways near oak ridge, Tennessee are also dual signed in metric and english units. I think it has something to do with the natiomal lab, but I dont know the history.
