Martin, Do road engineers use metric units or English units in the UK? Why are some of the signs metric and others in miles? Is there some logic to this? Why not be completely one way or the other? Are these markers used on all roads or just some roads? What type of road is a motorway?

A real mess you might say. However, with the advent of the mobile telephone, the emergency services found that very few motorists realized that positions on motorways could be pinpointed to within 100m by referring to the small marker posts, so new Driver Location Signs have been introduced, which are posted at 500m intervals. See http://www.highways.gov.uk/business/14730.aspx for a picture of both. You will notice that the word “kilometre” does not appear anywhere on that page, though there is a small mention of the word on the associated FAQ page. The sign on the off-ramp from the motorway to my home town shows 55.7 in large letters. ________________________________ From:[email protected] [mailto:[email protected]] On Behalf Of Jeremiah MacGregor Sent: 25 January 2009 17:55 To: U.S. Metric Association Subject: [USMA:42540] Re: Small item seen on TV Mike, From your description I would understand it to be that metric is used everywhere but on road signs. But road signs must be both if Martin said he was 55.7 km from London or did he just do a conversion? So people do speak in metric and don't really need to have things dumbed down as some one put it earlier. Your comments about pilots in the US explains why the last time I flew in a plane, the pilot hesitated before saying the temperature.. He must have been trying to translate it from what was on his screen.

Fuel is sold in liters, road signs are all in miles and miles per hour but all road work is done in meters. In general it seems like a big mess which is why here in the US we need to do it differently, Australian/New Zealand and South Africa did a very good transition in the 60's and 70's. Most young people in those countries don't know non metric units. I'm a pilot, when I fly into the UK the atmospheric pressure is in hPa, the visibility is in meters, the runway length is in meters/feet. Temperature is Celsius, it's also Celsius for all pilots in the US . Call 703 661 2990 here in the US to listen to the weather pilots get at my local airport.

Or is there more of a leaning towards one or the other? How are both use equally without causing confusion? Say for instance in the medical field. Would a doctor speak metric and a nurse respond in English? It must make for some strange communications.

It doesn't mean the is no psi, it just means it isn't very common. If the UK is metric then why would psi dominate and not kPa?

(100 kPa = 1 bar). ________________________________ From:[email protected] [mailto:[email protected]] On Behalf Of Jeremiah MacGregor Sent: 24 January 2009 14:59 To: U.S. Metric Association Subject: [USMA:42430] Re: Small item seen on TV Harry, Aren't they suppose to be in pascals or something along that line?

One showed pressure in kg/cm2, and the other in "bar".
