Default Any advantage of METRIC bars over IMPERIAL psi?

I don't understand why Japan (and others) use Metric instead of breaking down the psi with imperial.

So the deal is: bar x 14.5038 = psi

And for metric boost gauges, they mark the bars at:
0, 0.5, 1.0, 1.5, and 2.0

Since the WRX stock boost is around 14.2, it would be inaccurate to read on a metric boost gauge because it would land in between .9 and 1.0, therefore, you would just have to guess which interval the needle is landing on in the hundredths of a bar

For instance, if you boost at 21psi, which is a fair standard for a lot of cars in Japan (unless im wrong?), you'd have to read 1.44 bars and tune it so the needle lands in between 1.4 - 1.5

I just think its kind of inefficient/stupid

Are there any math tricks you guys use to convert bars to psi by looking at the gauge?

Someone enlighten me if I'm missing something.

I guess its easy to say 1 bar = 14.5psi and go up by ~1psi each .1 bar.

But still, it is not as precise which is why I rambled about it.

the real deal is that the rest of the world is far ahead of the US by using the metric system. THe imperial or "english" units we use are inaccurate and can become quite cumbersome when dealing with them. Anyone who has had a Thermodynamics class can vouch for that. The english unit system will never be as easy or accurate as the metric system. The reason they use bar's and Pascals over the ocean is because it is easier and alot more accurate. They please the Americans by humoring them with PSI gauges...as for learning tricks and such.. I don't think of how much PSI I am at.... I think of how many Mega-Pascals (MPa) I am at...when I am at .09 MPa, I know that I am pushing 13.05 PSI...

accuracy would be determined by what brand is moving the boost gauge needle

where the needle lands on and how easy your boost is readable, whether its PSI or BAR is what I'm talking about

I'm at 1.1 bar = 15.95418 psi
If I wanted 16 boost, I'd rather have a boost gauge that has a 16 on it...thats all I'm saying
