Can somewhere show me the dimensional analysis of this?

The pressure inside of a can is 245mmHg. What is the pressure in kPa?

245 mm Hg = 32.6634 kPa

Explanation:

When the pressure inside the can is measured in mm Hg and it is needed to convert mm mercury (Hg) to kilo pascal, we have to multiply the pressure in mm Hg with 0.13332, so that the pressure is converted in kilo pascals.

1 mm Hg * 0.13332 = 1 kPa

245 mm Hg * 0.13332 = 32.6634 kPa

So the pressure in mm mercury is converted into kilo pascals.
