Question

How pressure is measured?

Answer 1

Pressure

Pressure is defined as the force applied per unit area.

$P=\frac{F}{A}$ where $F$ is the force applied and $A$ is the area.

Pressure can be measured using the following standard units:

1. The derived unit of pressure is $N/m^2$.
2. This is also termed as the SI unit of pressure is pascal or $Pa$.
3. The atmospheric pressure is measured in $1atm$ which is equivalent to $760mm$ of $Hg$.
4. $1atm$ is also termed as $1bar$ of pressure.
5. $1bar={10}^{5}Pa$
