Air pressure is measured in which of the following units?

A) Steridian
B) kg/mts
C) Newton
D) Pascal

Answered by admin @ 04/08/2021

answer : option (D) Pascal

explanation : air pressure is measured by Pascal. Pascal is SI unit of pressure.as you know, pressure is the ratio of applied force and cross sectional area.

so, pressure = applied force/cross sectional area

si unit of force = Newton

si unit of area = m²

so, si unit of pressure =Newton/m² or N/m². to honour of great scientist ‘Pascal’ SI unit of pressure is known as Pascal. e.g., 1Pascal = 1N/m²

hence, option (B) is correct.
