Norton is close to correct.

85k quoted in Dadant list (per Thorne), for 11 Hoffman in the brood.

Foundation sizes are quoted as 10.75 (for brood) and 5.75 (for super).

Sooo, assuming you might lose about 0.5 (at top and bottom bars)

We have: 85k *5.25/10.25 for 11 frames = 43.5k (that is if brood were shortened to super depth).

With only 10 frames instead of 11, that would be reduced to 39.5k (former result divided by 1.1 before rounding).

Hazem, not sure where you are getting 50,000 cells per frame!

Onge, not sure where the 19 inch frame comes from? Length of top bar presumably?

Looks like the raw data were only to the nearest 100 cells, at best, so the answer would not be better than plus or minus, say, 250 and be a theoretical value.

Hope this helps.
