Thus enabling https://tvtropes.org/pmwiki/remarks.php?trope=Main.UnitConfusion#comment-87520:

[...] obfuscated measurements like the becquerels per diopter, which is just a roundabout way to describe meters per second. The becquerel measures frequency, with n becquerel meaning "n per second", while the diopter is used for lenses, with a n diopter focusing parallel light rays 1/n meters away from it. Technically, that means "becquerel per diopter" is "(1/s) per (1/m)", or m/s.
