Question

Formula of $1$ pascal.

Answer 1

Formula of $1$ pascal:

1. Pascal is the unit for measuring pressure.
2. Pressure is defined as the force per unit area.
3. The unit of force is newton or $N$ and the unit of area is $m^2$.
4. Hence, the unit pascal can also be written as, $1Pa=1N/m^2$
5. There are several interconvertible units of pressure:

5.1 $1atm=1.013\times {10}^{5}Pa$

5.2 $1bar={10}^{5}Pa$

5.3 $1atm=760torr$

5.4 $1torr=1mmHg$
