At the altitude of 8,000 ft (2,438 m) the pressure is 1,572 pounds per square foot or 75 kilopascals.
The Transition Altitude (TA) in France is generally 3000 FT AGL (above ground level). But most controlled airspace (TMA) uses another TA (4000, 5000 or 6000). The TA is printed on the official maps. Or you cold listen to ATIS. Or just ask a controller when unsure ...
No, the pressure decreases and you go higher into the atmosphere because the "air" is less dense....there is more space, but less molecules interacting with one another. Nearly half of the atmosphere's mass is contained to the first 18,000 FT (near 500mb) which is also a function of both gravity and the structure of chemical components within layers of the atmosphere. I hope that helps a little.
The altitude of Divide, CO is approximately 9,165 feet above sea level.

That is correct. If you think of the air as being a column of molecules, you can visualize that the mass of molecules in that column is forced downward by gravity. A 1cm square column extending upward to the top of the atmosphere weighs approximately 2.2 pounds. At an altitude further up the column where fewer molecules comprise a lesser mass they would exert proportionately less force. Another way to measure the weight of this column of air is by the pressure it exerts at a given point. Temperature also has an effect on the pressure of air due to a change in the density of the air mass, thus two columns of air at at the same altitude might have different pressures because their temperatures are different. Generally, cold air has a higher pressure than warm air at the same altitude. The decrease in pressure as altitude increases is called the pressure lapse rate, and has been tabulated for a "standard atmosphere" (one where the pressure and temperature at sea level are 29.92 in Hg (inches of mercury) and 15 deg C respectively). Obviously, this varies in real world conditions but is approximately 1 in Hg per 1000 ft. The term lapse rate also applies to temperature changes with altitude and is approximately 2 deg C per 1000 ft on average depending upon the the moisture content of the air.
Pressure altitude is the altitude above the standard datum plane where the altimeter is set to 29.92 inHg. If the altimeter setting is 30.00 inHg at 1000 ft, the pressure altitude would be lower than 1000 ft since the altimeter setting is higher than standard.
At 5,000 feet above sea level, the barometric pressure is typically around 18.7 inches of mercury (Hg) or approximately 630 millibars (mb). This value can vary based on local weather conditions and temperature. As altitude increases, air pressure decreases due to the thinner atmosphere. Generally, pressure decreases by about 1 inch of mercury for every 1,000 feet of elevation gain.
I think you have this question wrong. '6000 ft is equal to 6000 ft. However, 6000 ft is 6000/5280 = 1.1363636..... mile ( decimals to infinity)
In general, barometric pressure, or atmospheric pressure, drops as you go up in elevation. For example, at 18,000 ft. above sea level, the average barometric pressure is about half the average pressure at sea level (see the related links for charts) However, barometric pressure also varies widely with the weather (weather charts almost always show the movement of low pressure and high pressure zones), so true barometric pressure cannot simply be calculated, but must be measured. In the United States, the National Oceanic and Atmospheric Administration provides hourly barometric readings for many locations across the country (see related National Weather Service measurement link)
6000 ft = 6000 x 0.3048 meters = 1828.8 meters
6000 sq ft = 557.42 sq metres (approx)

Most likely, neither. When an airplane is flying above FL 180 (18,000 feet above sea level, or 18,000 MSL) in the United States, the altimeter readings are read out based on 'pressure altitude'.Normally altitude is determined by an instrument (altimeter) that utilizes the barometric readings reported at ground reporting stations over which you are flying. However, when cruising at or above FL180, pilots use 'pressure altitude', where the altimeter is set to use 29.92 inches Hg as the barometric pressure for readings. This helps to prevent having to change the instrument settings continuously to match the ground stations, and ensures that pilots flying at these higher altitudes all have the same reference setting for height.
20 ft
6,000 square feet is a little more than 1/8 acre. 43,560 sq ft = 1 acre 6000 sq ft = 6000/43560 acre = 0.13774 acre.
Answer: 6000 m² = 64,583.462 ft²
1 acre = 43560 sq ft 60 ft x 100 ft = 6000 sq ft = 6000/43560 acre = 50/363 acre ≈ 0.138 acre
