For a more formal tone, you could use alternatives such as "ascertaining if", "determining if", or "establishing whether", depending on the specific context.

What is the difference between "knowing whether" and "knowing if"?

While both phrases are often used interchangeably, "whether" is generally considered more grammatically correct when presenting two or more alternatives.

While including "or not" after "knowing whether" can sometimes add clarity, it is not always necessary. It's generally used when explicitly emphasizing that there are only two possibilities. For example, "knowing whether to proceed or not" clarifies the binary choice.

How to use "knowing whether" in a complex sentence?

You can use "knowing whether" to introduce a noun clause that serves as the subject, object, or complement of a verb. For instance, "Knowing whether the data is accurate affects the entire analysis," where the entire clause acts as the subject of the verb 'affects'.
