For A pressure of 25.7 inHg would be how many kilopascals?

25.7 mmHg x (101.325 kPa/760.0 mmHg)

The mmHg cancel each other out
So
98.659 kPa

My Question is I started out with inHg, and not mmHg. Would it be the same since I'm starting with inHg? or do I have to use different numbers. I know mmHg eqaula 760 torr

No, 25.7 inches must be converted to mm first. There are 25.4 mm in 1 inch.
