I know you were talking about a mountain or something, but "climb to <altitude>" does make one think about this exchange which would be in feet, not meters:
"climb to FL20 and the flying dinosaur thing will break" could work though
Since, annoyingly, international altitudes are done in increments of 1000 feet (ish, handwaving)
