Question

1 millibar is equivalent to :

• A. $100$ $N{m}^{-2}$
• B. $10$ $N{m}^{-2}$
• C. $1$ $N{m}^{-2}$
• D. $\frac{1}{100}$$N{m}^{-2}$

Answer 1

The correct option is A $100$ $N{m}^{-2}$

1 millibar = ${10}^{-3}$ bar

& 1 bar = ${10}^5$ Pascal

so ${10}^{-3}$ bar = ${10}^2$ Pascal

1 millibar = ${10}^2$ Pascal

1 millibar = ${10}^2{Nm}^{-2}$
