What it means
How high is that?
A flight level is a pressure altitude on the 1013.25 hPa standard setting, not a height above the ground. On a cold day the aircraft is genuinely lower than the level says.
The math
How to convert ft to FL
To convert feet to flight levels, multiply by 0.01.
Example: 350 ft × 0.01 = 3.5 FL.
In the other direction, 1 FL = 100 ft.
