pressure conversions?

Question

i need help with pressure conversions! from mmHg to kPa or atms or ugh anything....is there a formula

Answer 1

1 atm = 760 mmHg
1 atm = 101.325 kPa
760mmHg = 101.325kPa

There is no formula.You need to use the conversion factors I listed.

For example lets say you have 500mmHg and you want to convert to atm. you Divide 500 by 760.

If you then you want kPa, you then multiply that number by 101.325

Answer 2

Maybe I can help but you need to look up the conversions.

I think 760 mm Hg = 1 atm
1 atm = 14.7 lbs/ in^2

Sorry I'd have to look up the definition of a Pascal it might be Newtons/ meter^2 but I'm just not sure about that.

Answer 3

You can use this formula (I've indicated the units in brackets)

P (N/m^2) = Rho(Density of mercury : kg/m^3) * g(acceleration due to gravity : m/s^2 ) * h (height of the mercury column : m)

converting the Height of the mercury column into meters, you can use this formula to calculate the pressure in Pascal (Pa)
