In OpenStreetMap API it says

They cannot enclose more than 0.25 degrees of latitude or longitude. The area covered by the largest possible bounding box (of 0.25 square degrees)


Floating point numbers in degrees, expressing a valid bounding box, not larger than the configured size limit, 25 square degrees

Simply degrees*degrees or put differently the South-North side of the bounding box measured in degrees times the West-East side of the bounding box measured in degrees. The value is simply an upper limit for size of the bounding box.

In practical terms you will not be able to actually retrieve (nor should you) such a large area in many places, please don't forget that the OSM API is an API for editors not for general data retrieval.
