What do Myanmar, Liberia, and the United States have in common? They are the only countries in the whole world that are not on the metric system. There is a reason practically all the world is metric. It's not because the metric system is less useful than SAE.
Actually if you had a clue you could see that the Metric system does not have any advantage over SAE, none and there are areas where SAE kicks Metrics azz.
Well, OK.....
How much heat energy is required to raise one quart of water 10 degrees Fahrenheit?
Vs..
How much heat energy is required to raise 1 liter of water 10 degrees C?
Or....
An object that weighs on pound on Earth is moved to a place in space where there is practically no gravity. How much force must be applied to accelerate it 10 feet/sec/sec?
Vs....
A 1 Kg object is moved to a place in space where there is practically no gravity. How much force must be applied to accelerate it 3 meters/sec/sec?
In both cases, someone who understands metric can answer the second question in 1 second flat. Try the first questions, time yourself, and let us know if it took you less than that.
Metric is vastly easier, and fully as precise as our system. But if you grew up on our system, the transition is painful. The worst situation is a helter skelter mix of the two, which is what we have in the US.
