How long is 90 degrees?

Answer 1

90 degrees has no length associated with it.

90 degrees is, most likely, a measure of an angle. The arms of the angle can be of any length - including infinite length. The distance across the angle depends on how far from the vertex you measure.

The question may refer to the distance between latitudes or longitudes but both depend on the size of the sphere. And, in the case of longitudes, the latitude at which the distance is measured (if not the equator).

90 degrees could be a measure of temperature but then it is even less likely that a length is associated.

90 degrees can refer to academic qualifications and the only associated questions I can think of are how long it takes to accumulate 90 degrees, or how long 90 scrolls might be.
