I haven't touched the airspeed cal yet so it is still in mph. Those numbers for anything other than temp and pressure are still stock numbers from Tracy. I converted the temps only to metric. The pressure I left in PSI, but calibrated them only due to sensor inaccuracies.
I always have the Dynon in knots and I recall that the comparison (after conversion) between the 2 always seemed close. Since I have changed the EM2 OAT to Celsius, I expect that the EM2 true airspeed will be inaccurate now so once I get flying again and get the important stuff out of the way (like learning to fly a taildragger), I'll play with the airspeed calibration using my Dynon as a standard and I'll see if I can get them to match in Knots. I'll post that info then.
Canadian aviation is an odd mix of metric and imperial measurements with speeds reported in knots, visibility in statute miles,
altimeter setting in "Hg, station pressure in millibars, altitude in feet but temperature/dew point is always in Celsius.
I suppose it is like that in most of the world outside of the USA.
I was 10 when Canada made the switch so while I understand both systems and at work as an instrument mechanic I deal exclusively in metric, I do have an odd mix of preferred measurements units myself. I prefer psi instead of kPa, but C over F, but speed and distance, I could care less. But metric is always easier when doing calculations, so the sooner we can all have a common standard the better.
I have noticed in recent years that industrial instruments from the USA have now switched to metric, which simplifies my job. Previously we had a mix of European instruments in metric, but US instruments in imperial or standard which also confused the issue with volume (why did the US need their own gallon?). Furlongs per Fortnight! :-)
