True.  600 km to destination, and I’m going 100 km/h.  Six hours.   Change the speed to meters per second, and the mental calculation becomes almost impossible.   Carleton   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bill Hooper Sent: Wednesday, January 25, 2006 21:41 To: U.S. Metric Association Subject: [USMA:35854] RE: Weatherbug     On 2006 Jan 24 , at 9:29 AM, Jon Saxton wrote: The whole km/h vs m/s debate ... makes me wonder how we got stuck with speeds measured on an hourly basis. ... Any thoughts?   The only speed measurements familiar to many people is the speeds at which they drive their automobiles. They measure those speeds in miles per hour or in kilometres per hour because they relate distances driven to time measured on a clock, predominately in hours.   Thus, I think they just are familiar with mph or km/h and usually don't think in terms of metres per second or feet per second or anything else.   Regards, Bill Hooper Fernandina Beach, Florida, USA ======================== SIMPLIFICATION begins with SI ========================
