Question

What is the SI unit of pressure? What is the atmospheric pressure at sea level? Convert normal atmospheric pressure into SI unit?

Answer 1

Pascal is the Si unit ,

At sea level atmospheric pressure is very high

Answer 2

The use of millibars is slowly giving way to the equivalent SI unit of hectoPascals (hPa). The mean atmospheric pressure at sea level is given equivalently as P = 1.013x105 Pa = 1013 hPa = 1013 mb = 1 atm = 760 torr.
