I do not know if I understood correctly. But here is the regular expression for the given strings:

 ^(\d+(?:\.\d{1,2})?)\s(m|day|year)\s=\s(\d+(?:\.\d{1,2})?|\?)\s(s|hour|day)$

Required with multiline flag in options.

You can check the correctness and test on this site systemtextregularexpressions.com
