Americans have clung proudly and stubbornly to the USA measurement system, resisting a switch to the metric system, despite the occasional catastrophe that might be avoided by getting onboard with the rest of the world. Now, the metric system has become an issue in the US presidential election.

Bringing the issue to the forefront was an article in the German tabloid Bild titled “I worked out with Obama!” In the article, Bild reporter Judith Bonesky writes of observing the candidate working out in the gym of the Ritz Carlton hotel in Berlin: “He goes and picks up a pair of 16 kilo weights and starts curling them with his left and right arms, 30 repetitions on each side. Then, amazingly, he picks up the 32 kilo weights! Very slowly he lifts them, first 10 curls with his right, then 10 with his left. He breathes deeply in and out and takes a sip of water from his 0,5 litre Evian bottle.”
