If I pointed out that the speed of light in m/s is exact and the number of metres in a yard is exact and proceeded to give the exact value of the speed of light in imperial units
For some time, they claimed that converting exact values as rational numbers (as opposed to conversions with a finite number of sigfigs) is not a routine calculation. (To be honest, I’m not sure I remember what eventually happened. [goes to check] Oh, yeah. The footnote stayed because we did find a citation. Not that I’d normally consider the personal website of a cryptographer as a reliable source, but still.)
