$\displaystyle 1 \ \text{atm} \rightarrow 1.03323 \ \text{kgf}/\text{cm}^2$

Then,

$\displaystyle p_{\text{atm}} = 90 \times \frac{1}{1.03323} = 87.1 \ \text{atm}$

 

[logistic_guy]

$\displaystyle 1 \ \text{atm} \rightarrow 14.696 \ \text{psi}$

Then,

$\displaystyle p_{\text{psi}} = 87.1 \times 14.696 = 1280.02 \ \text{psi}$

$\displaystyle 1 \ \text{atm} \rightarrow 101.325\ \text{kPa}$

Then,

$\displaystyle p_{\text{kPa}} = 87.1 \times 101.325 = 8825.41 \ \text{kPa}$

 

[logistic_guy]

$\displaystyle 1 \ \text{atm} \rightarrow 1.01325\ \text{bar}$

Then,

$\displaystyle p_{\text{bar}} = 87.1 \times 1.01325 = 88.25 \ \text{bar}$
