Question

ok so i got a "U" on my lab cuz i didnt know how to covert air pressure inches to milibars. ik u can multiply by 33.86 x the air pressure but isnt there another way?? please help!!

ex (30.21) then what do i do from there??

Answer 1

You should have an ESRT (Earth Science Referance Table) and there is a chart that converts it for you.....just flip through it until you find it

Answer 2

29.92 inches of mercury = 1013.2 millibars

So to convert from inches to millibars multiply by 1013.2/29.92
