What is the SI unit of pressure

  • A.Pascal
  • B.Dyne
  • C.Newton
  • D.Joule

Answer: A

The SI unit of pressure is the pascal.

\[1\ \mathrm{Pa} = 1\ \mathrm{N\,m^{-2}}\] It is a small unit - atmospheric pressure is about \(10^{5}\) Pa. The dyne and the newton are units of force, and the joule of energy.
