What altitude is 200mb?
An air pressure of 200 millibars is said to occur near 39,000 feet (12,000 meters) in elevation. But the height ranges from near 35,000 to 41,000 feet (10,800 to 12,300 meters).
What is the altitude at 500mb?
The 500 mb chart represents weather conditions in the mid- troposphere, at a level where approximately half the mass of the atmosphere lies below this level. This level is at an altitude of approximately 5,500 meters (18.000 ft) .
How cold is it at 7000 feet?
Standard atmospheric pressure at sealevel = 29.92 inches of Hg. Temperature — As air is warmed, it expands and thus has a lower density. Hot air rises, which is what keeps hot-air balloons up, and cold air sinks. Standard atmospheric temperature at sealevel = 59.0°F.
What is the temperature at 20000 feet?

What altitude is 700 MB?
An air pressure of 700 millibars is commonly said to occur near 10,000 feet (3,100 meters) in elevation. But the height typically ranges from near 7,700 to 10,500 feet (2,350 to 3,150 meters).
How many MB is 10000 feet?
It is important to have an understanding of the average height of each of these important levels. 1000 mb is near the surface (sea level), 850 mb is near 1,500 meters (5,000 ft), 700 mb is near 3,000 meters (10,000 ft), 500 mb is near 5,500 meters (18,000 ft), 300 mb is near 9,300 meters (30,000 ft).

What altitude is 700 hPa?
Also known as a millibar (mb), hPa is a unit of pressure. By roughly 5,000 feet in elevation, the pressure has declined about 15% to approximately 850 hPa. Ascend to about 10,000 feet and the pressure drops to roughly 700 hPa, with 30% less air pressure and oxygen.
What altitude is 850 MB?
This pressure level is near an elevation of 5,000 feet though it ranges from 3,800 feet (1,170 meters) to 5,200 feet (1,590 meters).
How do you convert hPa to altitude?
Multiply the atmospheric pressure in hectopascals times 100 using a scientific calculator. For example, the pressure is 1037 hPa: 1037 x 100 = 103700. Divide your answer by 101325 using a scientific calculator. For example, 103700/101325 = 1.2034.
How do you calculate pressure altitude?
To calculate pressure altitude without the use of an altimeter, subject approximately 1 inch of mercury for every 1,000-foot increase in altitude from sea level . For example, if the current local altimeter setting at a 4,000-foot elevation is 30.42, the pressure altitude would be 3,500 feet: 30.42 – 29.92 = 0.50 in.
How do I read a 500 MB map?
Contour maps of 500 mb height are interpreted in the same way as topographic maps of ground surface elevation. Every point on the same contour line has the same 500 mb height. For example, locate the 576 dam contour line on the map above. This line snakes across the map.
