How do you convert rpm to psi?

You will need some other measurements to make it possible, since those are two different units of measurement. mph (or Miles Per Hour) is a measurement of speed, whereas psi (or Pounds Per square Inch) is a measurement of pressure. There is no direct conversion between them, however, if you know the volume of flow and the area it has to flow through, it should be possible to calculate.

For example:

A leaf blower rated at 450 cfm @ 250 mph when blowing through a 4 inch diameter pipe will produce "x" psi.

So you need the flow rate and diameter to finish the conversion.

The conversion from mega Pascal's to pounds per square inch is relatively simple. There are 145.0377 psi per MPa, so to convert, simply multiply that number by the number of mPa.

An mpa is a millipascal. The unit of a Pascal is 1 kg/(m s^2). So a millipascal is 1 gram/(m s^2). In converting a millipascal to pounds per square inch, 1 mpa is equal to 1.4504 E(-7) psi.

Take the number of mmHg multiply it by 14.7 then divide that number by 760.

PSI (pounds per square inch) units are different than mph units. However If you are talking about wind speed, the pressure of the wind against an object is PSI = 0.000018 x mph squared

It doesn't make sense to convert that. PSI is a measure of pressure. mph is a measure of speed.
