Now, how many of you can tell me how many tenths of a second fit into 5 minutes? I can't figure it out!
Well... 60 x 5 = 300 (that's how many seconds in 5 min.)
300 x 10 = 3000 (that's how many tenths of a sec. in 5 min.)
Awesome, thanks. Now, how many eighths of a second fit into 256 years?

Depends on which 256 years, with leap years and the year 2000 non leaped leap year, "calender" vs "solar" vs "astromomical" years, and all.

I get:
64,585,728,000 with 365 day years,
64,629,964,800 with calender leap years,
64,629,273,600 if year 2000 is one of those 256 years.
And I'm ignoring the calender "fix" needed to adjust for incorrect leap year, done some 200 or so years ago; that calender "year" was shorter by ~2 year IIRC. And the ~1/10th of sec "leap" year some sientists want at some point.
Call it ~64.6 billion eighths of a sec in 256 years, plus or minus 30 million.
