Why is the height "/1000"?

Homework Statement



In the attached example problem, why did the height, originally in millimeters then converted to meters, be divided by 1000?

Note: This is a thermodynamics related question? Or at least from a thermo textbook.

I thought that the units were fine when using 0.750 m.

The equation is poorly written, IMO. The /1000 at the end is to convert from Pa to kPa. It's not an attempt to convert mm to m, since they did that with the 750mm = 0.750m already. If they would have put parens around the whole numerator, that would have made it a bit clearer. Better yet, they should have used parens, and then multiplied by 1: 1 = 1kPa/1000Pa
