From the database I run for only series I've completed:

Documented:

9541 episodes

75 movies

31 shows with episodes not listed yet.

Anime series/movies not in database that I've seen: 184

So...

9541 episodes x 24 min: 228,984

75 movies x 90 min: 6750

31 (unlisted) x 13 eps (prefer to under ball it) x 24: 9672

Ratio of series/movies: 17% movies.

Undocumented:

Movie est: 32 x 90: 2880

Series: 152 x 13 x 24: 47424

Total: 295,710 minutes.

Converted: 205 days and 510 minutes.

To go one step more....

28 years x 365 = 10220 days

2% of my life has been spent watching anime.

I swore it would have been more.

Edit: Forgot to multiple series undocumented by 13.
