1) Convert pounds per square inch (psi) to millimeters of mercury (mmHg).

760 mmHg = 14.7 psi


mmHg=34\text{ }psi*\frac{760\text{ }mmHg}{14.7\text{ }psi}
mmHg=1757.82\text{ }mmHg

2) Rounding the result.

Since 34 has two significant figures the result must have two significant figures.

34 psi are 1800 mmHg.
