As opposed to what? The square root of -1 money? :-P

As opposed to new money. £sd -> £p.

It's useful for quick estimations involving water (one of the most common
pressurised fluids you come across) because it's a multiple of 10.
eg a water tank 4 metres above the tap, pressure at the tap is 0.4 bar.
or, 2 bar coming into your house, what's the pressure at the valve in your
roof 6 metres up? 1.4 bar

You mean that when you dive, each 10 meters of depth adds approximately
1 bar of pressure?

Yes, that's the only place I've encountered the term.
IIRC, a "bar" was picked as a "bar of mercury", i.e., one atmosphere? Except
then normalized to nearby SI units?
