The bar is a metric unit of pressure defined as 100,000 Pa (100 kPa), though not part of the International System of Units (SI). A pressure of 1 bar is slightly less than the current average atmospheric pressure on Earth at sea level (approximately 1.013 bar).
A centimetre of water [1] is a unit of pressure. It may be defined as the pressure exerted by a column of water of 1 cm in height at 4 °C (temperature of maximum density) at the standard acceleration of gravity, so that 1 cmH 2 O (4°C) = 999.9720 kg/m 3 × 9.80665 m/s 2 × 1 cm = 98.063754138 Pa ≈ 98.0638 Pa, but conventionally a nominal maximum water density of 1000 kg/m 3 is used, giving ...
The ambient pressure at sea level is approximately one atmosphere, which is equal to 1.01325 bars (14.6959 psi), which is close enough for bar and atm to be used interchangeably in many applications. In underwater diving the industry convention is to measure ambient pressure in terms of water column.

It would also improve sampling protocols used by public water systems. All of this, a monumental task, especially for cities like Chicago. "We're number one in the country, 400,000 lead service lines.

The metre (or meter) sea water (msw) is a metric unit of pressure used in underwater diving.It is defined as one tenth of a bar. [1] [2]The unit used in the US is the foot sea water (fsw), based on standard gravity and a sea-water density of 64 lb/ft 3.
