Could you please list the steps on solving it.

Thanks

This is what I get:

25.7 mmHg x (101.325 kPa/760.0 mmHg)

The mmHg cancel each other out

So

98.659 kPa

This is 25.7 INCHES which must be converted to mm before the rest of the conversions are done.

See posts above for the correct answer.

Sorry misunderstood, I thought in was "in" not inches assumed it was mm.
