Halves-lives and average lifetimes, when studying nuclear decay, are often expressed in years even though years are not standarized, at least in SI (as far as I know). Borrowing the convention from astronomy and astrophysics, I usually take 1 \mathrm{yr} to be equal to 365.25 days of 86400 \mathrm{s}, so a Julian year. I'd like to know, however, if there is a convention in nuclear physics concerning the equivalent in seconds of a year. Thank you in advance for your time!
