Former Soviet Union countries utilize altitude in meters and China also gives altitudes in meters . There are conversion charts depending in which country you are flyingg, but you are given altitude in meters and you reference the chart and get the conversion in feet.
US registered aircraft still follow these procedures when flying in these countries.
Ah ok, makes sense. But do all Chinese A/C use meters? If so that ought to be confusing for all the expat pilots who are used to feet
