What is the correct unit for labeling work? help pls

Answer:
Often, data values stored in structures will be accompanied by textual labels describing what they are and what units they are represented in. Whilst this paper describes abstracted data structures, clearly the main use of the data formats is for astronomical data. Therefore, it is important that the form and content of these label and units strings conform to a definite standard, so that they are readable and unambiguous.
One important reason for consistency is so that those general-purpose applications which have more than one input data array can test for equality the units of the various associated data objects. For utility operations, like addition and subtraction, the application must warn the user if the units are different, and where an output object is being generated must drop the units altogether. In other cases it may not be possible to proceed with the processing at all.
A minor reason for a rather definite standard is that future applications (but not the present ones), may have the capability of interpreting and processing labels and units. For example, consider a hypothetical application which would calibrate an array of data by dividing into it another array containing the calibration information. The attributes of the two arrays, and the result, [FLUX] might be:
