Interesting site this.
Charlie Chaplin once entered a 'Charlie Chaplin Look-a-Like Competition' that was occurring in France; unfortunately, he only came third.
The international yard is defined as exactly 0.9144 metres. This definition was agreed by the United States, Canada, the United Kingdom, South Africa, Australia and New Zealand through the international yard and pound agreement of 1959.
The US survey foot and survey mile have been maintained as separate units for surveying purposes to avoid the accumulation of error that would follow replacing them with the international versions, particularly with State Plane Coordinate Systems. (The choice of unit for surveying purposes is based on the unit used when the overall framework or geodetic datum for the region was established, so that - for example - much of the former British empire still uses the Clarke foot for surveying.) The US survey foot is defined so that 1 metre is exactly 39.37 inches, making the international foot of 0.3048 metres exactly two parts per million shorter. This is a difference of just over 3.2 mm or a little over one eighth of an inch per mile.
The main units of length (inch, foot, yard and international mile) were the same in the US, though the US rarely uses some of the intermediate units, such as the (surveyor's) chain (22 yards) and the furlong (220 yards).
At one time the definition of the nautical mile was based on the sphere whose surface is the same as the Clarke Ellipsoid. In the US, the full value of 1853.256 metres was used, but in the Commonwealth, this was rounded to 6080 feet (1853.184 m). These have been replaced by the international version, which rounds the sixtieth part of the 45° to the nearest metre, as 1852 metres.
Just sayin like

Yes, a mile is 8 furlongs = 1760 yards (x .9144)= 1609.3 metres (1.6093 km)
A nautical mile is 1 minute of distance at the 0 latitude. There are 360 degrees in a circle and 60 minutes in a degree = 21,600 minutes in a circle. At the equator, (i.e. latitude 0) the Earth has a circumference of 24,857 miles therefore each minute represents (25000/21600) =1.1508 miles=1 nautical mile. The marine velocity unit ‘knot’ = 1 nautical mile/hour.
Thus 10 knots =10 nautical mph= 11.508mph= 18.52 km/hour i.e. (11.508 x 1,609.3 metres)/1000
With the US, Not only did we have 2 nations separated by a common language, we had 2 nations separated by a common system of measurement.
Over the years tiny accumulated errors, both up and down had crept in to measurements on both sides of the atlantic.
Resulting in during the war...in simple terms... a US half inch bolt would not go in a half inch UK hole. 2thousandths of an inch (0.002in) 1thousandth of an inch on each side of the atlantic, is all it takes.
The Brits had to send over their own UK micrometers and such for the Yanks to use to make the parts they sent us.

yes, the americans did implement use of a metric system (1950s?)that ran parallel with their old imperial system- but it wasn't compulsory and so, inevitably, it never gained traction.
But even in 'old', non metric measures, there is a difference between US and Commonwealth countries eg their ton is different, as is their gallon.
Too late to syncronise things now imo...that horse has bolted (by way more than 2/1000ths of an inch! lol)

interesting. The density of steel is typically 8g/cc (8tonnes/cubic metre). Mercury's density is higher 13.5g/cc...hence steel floats. Gold would sink.
Stop spamming the forum please
Proper facts them, not like the rubbish we get now.

Gold would also dissolve in the mercury to form an amalgam, whereas steel would not - iron a notable exception as a metal that does not amalgamate with mercury.
