Question

what is SI unit of pressure ? what is atmospheric pressure at sea levek? convert normal atmospheric pressure into SI unit.​

Answer 1

Answer:

1. Some common units of measurement this Pressure Conversion chart helps you convert are: atmosphere (atm), bar (b), Dyne (dynes/cm²), hectopascal (hPa), kilogram per sq. cm (kgf/cm²), kilogram per sq. meter (kgf/m²), kilopascal (kPa), millibar (mbar), millimeter of mercury (mmHg), pascal (Pa), pounds per square foot.  
2. Standard sea-level pressure, by definition, equals 760 mm (29.92 inches) of mercury, 14.70 pounds per square inch, 1,013.25 × 103 dynes per square centimetre, 1,013.25 millibars, one standard atmosphere, or 101.325 kilopascals.
3. The SI unit for pressure is the pascal (Pa) and is equal to one newton per square meter (N/m2 or kg/m.s2 - prior to 1971 the unit was simply known as N/m2). Non-SI measures in common use are pounds per square inch (psi) and bar. In cgs units the pressure is expressed as the barye (ba). One barye is equal to 1 dyn/cm2.

Answer 2

Explanation:

SI unit of pressure is pascal (pa)

conversion is between atm pressure into SI unit is as followes

p = 1.013×105 pa = 1 atm pa
