Certainly not "worldwide". China uses metres. Recreational aircraft in Europe often use metres (almost all sailplanes).

Thank you, I wasn't aware of China using metres. It turns out Russia uses them as well, confusingly below the transition level.
No glider I have ever stepped in used metres. It doesn't make any sense, the tower wants to hear feet and knots and will communicate using that.
