In China we ran a mix of AS332s. The ASIs could be in either knots or KPH, the altimeters in feet or metres with ATC allocating altitudes in metres, the RCDIs in ft/min or ms/sec and the pressure gauges in lbs/in or bars. Our loads were delivered in kilos and had to be converted to lbs.
Fortunately most of them had fuel gauges that with a flick of a switch read in either lbs or kilos.
