@A C - I've seen this on TV but never IRL. While I assume it's rare, I also assume there are some folks who have seen it on TV, thought it was cute, and decided to try it at home.

@Nick, Hard disagree. Imprecise correspondence can be acceptable when there's some context to justify it. A one-word clue, however, really needs to be synonymous with the answer. IMO.

@Nora, Until 2019 it was considered a "compatible unit" and was still widely used despite not being an official SI unit. The International Bureau of Weights and Measures began officially discouraging its use following the 2019 update of the SI standard.

Agree. Tuesday-easy. Did this one get published with the "Easy Mode" clues, or what? Lovely puzzle, but not Friday difficulty.
