Hi everyone here we have a question telling us that a category three hurricane can have a central pressure up to 964 millibars and a wind speed of 130 MPH. Based on the Saffir Simpson scale, what is the pressure in inches of mercury? So there's a few conversion factors we need to know for this one. One millibar equals 10 To the negative. three bars, one atmosphere Equals 1.01325 bars, one atmosphere Equals 760 milligram millimeters of mercury, and one inch of mercury equals 0. millimeters of mercury. So now we're going to set up our equation. So we're starting off with our mill bars and we're going to multiply that by 10 to the negative three bars over one millibar. And we're going to multiply that by one atmosphere Over 1.01325 bars. And we're going to multiply that by 760 millimeters of mercury over one atmosphere. And we're going to multiply that by one inch of mercury over 25.4 millimeters of mercury. So our millibars are canceling out. Our bars are canceling out, our atmospheres are canceling out and our millimeters of mercury are canceling out And that equals 28. inches of mercury. And that is our final answer.
