# Why is the height /1000 ?

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.
