How do you convert 2.8 atm to psi?

${\text{1 atmosphere"= 14.70*lb*"inch}}^{-} 2$
So $2.8 \cdot a t m$ $=$ $2.8 \cdot a t m \times 14.7 \text{ psi } a t {m}^{-} 1$ $=$ ??"psi"
Note that there is an added complication. Sometimes, $\text{psig}$ is used, which stands for $\text{pounds per square inch gauge}$, where $\text{0 psig}$ $=$ $1 \cdot a t m$. You might have to call a plumber.
