Misleading phrase about change
“Germany moved to using the new candle (NC) from 1 July 1942 and the candela (cd) from 1948.” - this sentence sounds like there were two moves in Germany. However, ther was only one move. NC (in Germany called NK = Neue Kerze) and cd are the same. It only was given the new name candela at the CGPM conference in 1948. — Wassermaus (talk) 08:01, 7 September 2021 (UTC)
