This was obviously <em>after<\/em> the US declared independence so had no effect over there.<\/p>\n\n\n\n<p>The US units were based on traditional English units which were chiefly defined by the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Exchequer_Standards\">Exchequer Standards<\/a> or the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Winchester_measure\">Winchester Standards<\/a> (technically there were several standards that could be called &#8220;Winchester&#8221; dating back to Alfred the Great). That is an oversimplification &#8211; various &#8220;laws&#8221; (the earliest ones were simple pronouncements of the monarch) covering weights and measures are within every single century from the 10th century onwards.<\/p>\n\n\n\n<p>The differences between US traditional units and Imperial units are subtle, but significant in the area of volume &#8211; Imperial units of volume don&#8217;t distinguish between &#8220;wet&#8221; and &#8220;dry&#8221;. A US wet pint is 473mL, a US dry pint is 550mL, and an Imperial pint is 563mL.<\/p>\n\n\n\n<p>So the old saying &#8220;a pint&#8217;s a pound the world around,&#8221; is complete nonsense.<\/p>\n\n\n\n<p>To throw more petrol (or gas) on the fire, both US traditional units and Imperial units are defined by legislation in terms of metric units, so as defined <em>today<\/em>, neither are proper units of measurement.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" width=\"695\" height=\"521\" src=\"https:\/\/i0.wp.com\/really.zonky.org\/wp-content\/uploads\/2020-05-27-no-fun-at-the-fair.jpeg?resize=695%2C521&#038;ssl=1\" alt=\"\" class=\"wp-image-5776\" srcset=\"https:\/\/i0.wp.com\/really.zonky.org\/wp-content\/uploads\/2020-05-27-no-fun-at-the-fair.jpeg?resize=1024%2C768&amp;ssl=1 1024w, https:\/\/i0.wp.com\/really.zonky.org\/wp-content\/uploads\/2020-05-27-no-fun-at-the-fair.jpeg?resize=300%2C225&amp;ssl=1 300w, https:\/\/i0.wp.com\/really.zonky.org\/wp-content\/uploads\/2020-05-27-no-fun-at-the-fair.jpeg?resize=768%2C576&amp;ssl=1 768w, https:\/\/i0.wp.com\/really.zonky.org\/wp-content\/uploads\/2020-05-27-no-fun-at-the-fair.jpeg?resize=1536%2C1151&amp;ssl=1 1536w, https:\/\/i0.wp.com\/really.zonky.org\/wp-content\/uploads\/2020-05-27-no-fun-at-the-fair.jpeg?resize=2048%2C1535&amp;ssl=1 2048w, https:\/\/i0.wp.com\/really.zonky.org\/wp-content\/uploads\/2020-05-27-no-fun-at-the-fair.jpeg?w=1390&amp;ssl=1 1390w\" sizes=\"auto, (max-width: 695px) 100vw, 695px\" \/><figcaption class=\"wp-element-caption\">No Fun At The Fair<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>One of the strangest things that comes up in discussions of metrification, is that US traditional units (&#8220;feet&#8221;, &#8220;inches&#8221;, etc.) are referred to as Imperial units.
