Definition. Flight levels [3] are described by a number, which is the nominal altitude, or pressure altitude, in hundreds of feet, while being a multiple of 500 ft, therefore always ending in 0 or 5. Therefore, a pressure altitude of 32,000 ft (9,800 m) is referred to as "flight level 320".
The National Airspace System (NAS) is the network of United States airspace, air navigation facilities, services, airports, regulations, procedures, technical information, human resources, and material shared jointly between the Federal Aviation Administration (FAA) and the military.
25 sty 2024 · A flight level (FL) is a standard pressure altitude, expressed as three numbers. Aircraft flying on flight levels all measure their altitude from the same pressure setting, 1013.2 Hpa (or 29.92 InHg). This is based on the principle of something called the International Standard Atmosphere.

FL180 and FL300 stand for Flight Level 180 and Fight Level 300. Flight levels are spaced 100ft apart on an altimeter that is set to the standard sea level pressure (QNE) of 1013.25 hectopascals or 29.92 inches of Mercury. So indeed, FL300 means 30,000 ft.
Flight Level is a standard altitude measurement system used in aviation. Unlike altitude, which is measured from the ground level, Flight Level is established based on a standard pressure reference, allowing for consistent altitude navigation regardless of atmospheric conditions.
Altitude. The vertical distance of an object measured from mean sea level. Flight Level (FL) A surface of constant atmosphere pressure which is related to a specific pressure datum, 1013.2hPa, and is separated from other such surfaces by specific pressure intervals.
