About Barye

The barye (Ba) is the CGS unit of pressure - 1 dyne/cm² = exactly 0.1 Pa = 1 µbar. Standard atmosphere = 1,013,250 Ba. It dominated physics and laboratory science from the mid-19th century until SI adoption. Legacy acoustic CGS literature used 1 barye (0.1 Pa) as the underwater reference pressure, creating a 100 dB offset versus the modern 1 µPa reference - a critical correction when comparing historical and modern underwater acoustics databases. Still encountered in classical fluid mechanics derivations and early 20th-century meteorological literature. 1 Ba = 0.1 Pa.

About Kilopascals

A kilopascal (kPa) = 1,000 Pa - the practical everyday SI pressure unit for moderate pressures. Car tyre inflation: 200-250 kPa (29-36 psi); truck tyres 550-830 kPa. Blood pressure in SI countries: 16/10.7 kPa (= 120/80 mmHg). Systolic blood pressure 16 kPa. Carbonated beverages are packaged at 200-500 kPa CO₂. Medical oxygen cylinders at 15,000 kPa; scuba cylinders 200-300 bar = 20,000-30,000 kPa. 1 kPa = 1,000 Pa = 0.01 bar = 0.145 psi.
