1 millibar = 0.0145037738 psi
0.973 bar
1 bar is approximately equal to 1 standard atmosphere (which equals 14.7 pounds per square inch, psi). 1 psi is approx 68.95 millibars (1000 millibars = 1 bar).
The actual conversion is: 29.92 in. Hg = 1013.25 millibars . . . both numbers represent standard sea-level pressure.
That is the correct spelling of millibar (mb) and it means "1/1000th of a bar" which is a non-SI unit of pressure, chiefly atmospheric pressure. A bar is defined as 100,000 pascals (100 kilopascals) so that "standard pressure" on Earth is 1.01325 bars, equal to 101.325 millibars.
169 millibars.
922.1 millibars.
33.8637526 1 Bar is an arbitrary "standard atmospheric pressure" which is roughly 29 and a half inches of mercury. If you multiply the inches-of-mercury value by 33.8637526 you get the pressure in millibars
922 millibars.
A Category 1 Hurricane has 980 Millibars or greater, however, to be a C1 Hurricane, its Wind Speed has to be 75-95 MPH.
1004 millibars is approximately equal to 29.65 inches of mercury.
30 millibars = ~0.435 pounds per square inch.
