How many feet in one alitatude?

Answer 1

It seems there might be a typo in your question. If you're asking about "altitude," it refers to a height above a specific reference point, often sea level, and is measured in feet or meters. If you meant "altitude," it doesn't convert to a specific number of feet; instead, altitude can be any value depending on the context, such as the height of a mountain or an aircraft. If you meant something else, please clarify!
