Convert a pressure of 23.8 in. Hg into kilopascal.
Ok so I looked up kilopascal and it Said 1 Kpa = 1000 pa
So I began to set it up like this 23.8 / 29.2 x1000 am I correct
I don't think that will get it. I would go this route.
23.8 inches x (25.4 mm Hg/1 inch Hg) x (1 atm/760mm) x (101.325 kPa/1 atm) = ??
There are MANY other steps that will work; I just use those conversion factors with which I'm familiar. I've memorized just a few conversions to help my tired brain.
DrBob222 I used 29.2 in Hg because my book gave me 1 atm = 29.92 in. Hg. But why did you use 1atm/760mm
To convert a pressure from inches of mercury (in. Hg) to kilopascals (kPa), you need to use the conversion factor of 1 in. Hg = 3.38639 kPa.
To calculate the conversion, you can use the formula:
Pressure in kPa = Pressure in in. Hg x Conversion factor
In this case, the pressure is given as 23.8 in. Hg. So, let's substitute the values into the formula:
Pressure in kPa = 23.8 in. Hg x 3.38639 kPa/in. Hg
Now you can perform the multiplication:
Pressure in kPa = 80.406 kPa
Therefore, 23.8 in. Hg is equal to approximately 80.406 kPa.
