british 'imperial' measures are derived from metric, an inch is legally 25.4mm, been that way a long long time, using imperial measures just adds complexity and opportunity for error
there's still a lingering issue in the usa, the foot they use for geodetic survey is not quite the same as the foot defined by 12*25.4mm used for everything else, one day they'll fix it
One inch does indeed equal 25.4mm but it was around for centuries beforehand.The above may be fact, or fiction, I may be serious, I may be jesting.

Yeh, the first time I did some geodetic work in the States the difference between the imperial and US foot caused some confusion until we realised what was going on. It's ppm, but becomes significant with precision work.
I believe the Mars orbiter buried itself with some vigour into the regolith IIRC.0 -

that's because the current inch is derived from the metric system, in uk law it is defined as 25.4mmpblakeney said:

https://en.wikipedia.org/wiki/InchBefore the adoption of the international yard and pound, various definitions were in use. In the United Kingdom and most countries of the British Commonwealth, the inch was defined in terms of the Imperial Standard Yard. The United States adopted the conversion factor 1 metre = 39.37 inches by an act in 1866.[25] In 1893, Mendenhall ordered the physical realization of the inch to be based on the international prototype metres numbers 21 and 27, which had been received from the CGPM, together with the previously adopted conversion factor.[26]
As a result of the definitions above, the U.S. inch was effectively defined as 25.4000508 mm (with a reference temperature of 68 degrees Fahrenheit) and the UK inch at 25.399977 mm (with a reference temperature of 62 degrees Fahrenheit). When Carl Edvard Johansson started manufacturing gauge blocks in inch sizes in 1912, Johansson's compromise was to manufacture gauge blocks with a nominal size of 25.4mm, with a reference temperature of 20 degrees Celsius, accurate to within a few parts per million of both official definitions. Because Johansson's blocks were so popular, his blocks became the de facto standard for manufacturers internationally,[27][28] with other manufacturers of gauge blocks following Johansson's definition by producing blocks designed to be equivalent to his.[29]
In 1930, the British Standards Institution adopted an inch of exactly 25.4 mm. The American Standards Association followed suit in 1933. By 1935, industry in 16 countries had adopted the "industrial inch" as it came to be known,[30][31] effectively endorsing Johansson's pragmatic choice of conversion ratio.[27]
In 1946, the Commonwealth Science Congress recommended a yard of exactly 0.9144 metres for adoption throughout the British Commonwealth. This was adopted by Canada in 1951;[32][33] the United States on 1 July 1959;[34][35][36] Australia in 1961,[37] effective 1 January 1964;[38] and the United Kingdom in 1963,[39] effective on 1 January 1964.[40] The new standards gave an inch of exactly 25.4 mm, 1.7 millionths of an inch longer than the old imperial inch and 2 millionths of an inch shorter than the old US inch.[41][42]0 -
Yes, so they standardised the length of an inch which happened to be 25.4mm.
Nobody in their right mind would pick that as a factor over 25mm.The above may be fact, or fiction, I may be serious, I may be jesting.

A bit of a surprise that British POWs have been released.
Not so surprising there have been widespread demos and arrests in Russia. Nothing says a war is going badly than a widespread mobilisation.0 -
