PRESSURE REFERENCES

1000 millibars (mb) = 100 kiloPascals (kPa) = 14.50 pounds per square inch (psi) and this is equal to about 99% of the average air pressure at sea level.
Pressure drops off with elevation. The reverse altitude atmospheric pressure
relation can be seen in the requisite levels which have these approximate heights
above sea level (ASL):
1000 mb ~ 360 feet (110 m)
1000 mb ~ 360 feet (110 m) 850 mb ~ 5000 feet (1500 m) 700 mb ~ 10,000 feet (3000 m) 500 mb ~ 18,000 feet (5400 m) 250 mb ~ 34,000 feet (10,200 m) Approximations: 1000 mb - sea level 850 mb - 5,000 ft 700 mb - 10,000 ft 500 mb - 8,000 ft 300 mb - 30,000 ft WEATHER ROOM NOAA WEATHER MAP SYMBOLS	850 mb ~ 5000 feet (1500 m) 700 mb ~ 10,000 feet (3000 m) 500 mb ~ 18,000 feet (5400 m) 250 mb ~ 34,000 feet (10,200 m)
