Homework Statement
A mercury barometer located in a room at 25°C has a height of 750 mm. What is the atmospheric pressure in kPa?
Homework Equations
Patm = ρ*g*H0
The Attempt at a Solution
[/B]
My question pertains to the units and how it ends up as kPa in the book. I have no problem with the calculations, just the unit conversion.
ρ*g*H0 = (13580 kg/m3) * (9.81 m/s2) * [ 750 mm * (1 m/1000 mm)]
= 99914.85 kg/s2*m ... <--- is what I got.
The book got 99914.85 Pa which translates to 99.54 kPa.
Is kg/s2*m another way to say kPa?
