Most times metric is more useful.Sometimes SAC is more useful, other times RMV is more useful. It's good to know how to convert either direction.

We’ll do that once the world adopts a new reserve currency.Most times metric is more useful.

At least the US Dollar is metric. Not like when I was young with 240 pence to the pound. I guess that system worked in the 800’s.We’ll do that once the world adopts a new reserve currency.
Nope. The original error came from ignoring ATA. Nothing to do with metric.Where the original error came from.
10m water => 1bar =>1 ATA , close enough for diving purposes. a lot easier than 33ft water=> 14.7psi => 1 ATA. You can do the RMV math in your head in metric.Nope. The original error came from ignoring ATA. Nothing to do with metric.
Sometimes metric is easier, sometimes not. We older engineers use whatever works, convert if needed, do a lot in our head (slide-rule generation), and don't proselytize.10m water => 1bar =>1 ATA , close enough for diving purposes. a lot easier than 33ft water=> 14.7psi => 1 ATA.

Even here in the States, all the competent engineers I know do the engineering in metric and then convert to whatever units requested.
I use metric for cooking and charcuterie.Most times metric is more useful.

You are right, I overstated my case. For problems with non-metric inputs and/or non-metric outputs, doing the engineering in metric is not always a good idea. Also when re-using existing engineering it can be a bad idea to switch units (see the recent death due to metric/imperial tank valve specs in another thread).Sometimes metric is easier, sometimes not.

No, you can convert depth to pressure in your head. Very few will calculate RMV in their head for using 153 bar out of a 11.1 l cylinder over 27 minutes at an average depth of 19 m.You can do the RMV math in your head in metric
