We have countries driving on the wrong side of the road steering wheel on the wrong side of the car ...( Mod Removed Langage) there hurricanes even spin the wrong way

While all other aviation uses imperial...?Being an American, miles, gallons and Fahrenheit makes sense to me. But curiously, when it comes to drones I prefer the metric system.
not those Americans like myself who don’t no it and doesn’t want to. It’s nice to see that this doesn’t matter as much to thoseAmericans who use it.
Pretty much the world follows what America does
Was good enough for the last few hundred years here.It’s not an issue for me- I will happily perform the conversion where I need to. What I find interesting is anyone might expect that a less universally employed system should be the preference. That is arguably the obsession to the extent one might be identified.

Military. The U.S. military uses metric measurementsextensively to ensure interoperability with allied forces, particularly NATO Standardization Agreements (STANAG). ... The Navy and Air Force continue to measure distance in nautical miles and speed in knots; these units are now accepted for use with SI by the BIPM.Excellent point! Since most 'skirmishes' take place over there . . . I'll have to look into that.
It’s nice to know three countries got it rightThe metric system is used in every country on earth except three of them: Myanmar (Burma), the United States, and Liberia . If we are going to venture out into the world . . . we'd better get on board with it. To me . . . it is a more logical system. Easier to calculate and simplify. Decimals versus fractions. I only use Imperial here in the USA but I understand metrics. I frequently deal with it in construction projects.
And they still use them even to the point of saying “Horse Power”So were horses.

I guess my point is at least if it’s good enough to still use in aviation here and this hobby is just that than why not.
Then why is it still used in aviationSo you eschewed motor vehicles and still drive a horse?
No one is telling you not to use it. But the imperial system of measurements is basically worthless in all multi-unit problems in science and engineering, because the products and quotients of values generally don't have simple appropriate units. That makes it very difficult and error prone to use. The metric (specifically S.I. version) is dimensionally consistent, supports just a few basic units, and is easy to error check.

Guess I’m just old school who doesn’t like change... guess I need to read Metric System for Dummies.Inertia? Lack of need? Changing the unit system across the entire aviation industry at once would be difficult and expensive. And the main disadvantages of the imperial system that I listed above are not really applicable to the few basic aviation measurements.

The Wikipedia page on the subject includes a pretty readable explanation of the advantages:International System of Units - Wikipedia
en.wikipedia.org
In aviation, most of the standard units of measure are imperial:
- Airspeed: Knots (nautical miles per hour)
- Distances: Nautical miles
- Altitude: Feet
- Fuel: Pounds
- Temperature: Celsius
Well, three countries still use different versions of the imperial system. The rest of the world uses metric. I wasn’t talking about the forum membership, but the planet in general."More widely used" -- I guess it depends on how you define that.
It would be interesting to generate some statistics of the members registered in this forum to see what is the "most widely used" measurement system simply based on those members.
