Yesterday, an editor at Fox News seems to have been cruising on automatic pilot when adding metric equivalents to an AP story on crash test results ("Small Cars Get Poor Marks in Collision Tests", 4/14/2009):
The tests involved head-on crashes between the fortwo and a 2009 Mercedes C Class, the Fit and a 2009 Honda Accord and the Yaris and the 2009 Toyota Camry. The tests were conducted at 40 miles per hour (17 kilometers per liter), representing a severe crash.
40 miles per gallon is 17 kilometers per liter.
