About this converter
Stargate episode counts are listed here from MGM lists. SG-1 runs 20 to 22 per sampled season: Season 8 and Season 10 at 20, Season 1 and Season 4 at 22. Atlantis runs a flat 20 across sampled seasons 1, 3 and 5. Universe runs 20 and 20. Infinity animated at 26 tops the table. Origins web series at 10 anchors the low series end. The two direct films each count 1 alone as film rows. Mid franchise totals stay consistent near 20 per season. All rows pin official lists.
How to use it
Pick two series and a unit in the top row. The three boxes below stay linked. Change any box and the other two update. One box holds a count of the first series, one holds the matching count of the second, one holds total episodes. Try Infinity against Origins.
Sampling keeps the table readable: SG-1 and Atlantis full runs follow the same 20 to 22 band as rowed samples. Pilot movies count inside season totals. Recut editions add no episodes and add no rows. Comics and novels stay out. Franchise marathons sum sampled seasons in results.
