Hi Paul,
Our internal door handles are 1 metre exactly above floor level, our external door handle is 1100 mm above floor level. _____ From: [email protected] [mailto:[email protected]] On Behalf Of Paul Trusten Sent: 22 January 2011 20:15 To: U.S. Metric Association Subject: [USMA:49572] the 1 m doorknob poll We sometimes use the height of a doorknob above the floor as a frame of reference for a height of 1 m. I just put that presumption to the test here in my apartment in Midland, Texas, USA, and I measure 950 mm from the floor to the tangent at the top of the doorknob collar. If you have a chance, please try measuring your doorknob height and see how it compares. Thanks, Paul
