That particular conversion is an easy one to remember for physicist, since you've long known that the speed of light is 3 x 10^8 m/s, or 300,000 km/s. But in grade school you were always taught 186,000 miles/second.
Happy (in another half houf) London New Year! Nat From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Han Maenen Sent: Monday, 2007 December 31 13:36 To: U.S. Metric Association Subject: [USMA:39971] Eurostar comes to a standstill The 300 km/h of the Eurostar were converted to 186 mph, that was back-converted to 299 km/h, and this ridiculous number has appeared in many English language newsitems. Now one can go on converting and back converting and in the end...... the Eurostar grinds to a halt! I wish everybody a fruitful 2008 and that this year may see real metric progress!
