<div id="ygrps-yiv-671416117">so our millimetric usnm value & waorus coords have a monte carlo start & finish & are dedicated to the ease & convenience of universal ready reference & so even if our 6th decimal place may be a little shaky i still believe we couldnt have done a more punctilious recovery job than 5 digits anyway even with the worlds best available gps technology so grant i believe you have broken the worlds record for best available tripoint coordinates anywhere<br/>

&gt; I know you&#39;re all losing sleep over this one, so here&#39;s the definitive<br/>
<br/>
&gt; scoop on the US nautical mile.<br/>
<br/>
&gt; In 1929 a conference in Monaco defined the &quot;international nautical<br/>
<br/>
&gt; mile&quot; as *exactly* 1852m. In 1954, this measurement was adopted by the<br/>
<br/>
&gt; US, but for ready reference the exact figure in metres was converted<br/>
<br/>
&gt; to feet, with the decimals extended as far as anyone felt it necessary<br/>
<br/>
&gt; to go: 6076.11549ft, rounded to the nearest couple of microns.<br/>
<br/>
&gt; So exact metres, approximate feet.<br/>
<br/>
&gt; Now we can all rest easy.<br/>
