9x12cm film equals 16 square inches per sheet?

After the minimum volume discussion, I thought about this as I am about to finally load my AVUS 9x12 camera and plan to use the P's 9x12 developing adapter for the 3 reel Patterson daylight tank, so I thought I should confirm how many sheets of 9x12 would equal the standard 80 square inches of surface area per 8x10, 120 roll and 36 exposure 35mm film cartridge.

I come up with 5 sheets with a single sheet coming in just under 16 square inches.

Fittingly, the P's adapter has 6 slots, so I think that was anticipated in the design and with a liter of developer capacity, I should be fine.

Found someone had measured a sheet as
88.5 x 118.5 mm

This works out close to what you say 16.25 sq in per sheet

Great. Thanks for the confirmation.

This matches what I recall when I measured it to ensure home-built tube tanks would fit the film.
