That is correct. Here is what Stecchini saw that made him think it was his modern meter of 39.37 ins. that was being used. The Roman Pes Aebutianus of 400,000 grs. as a cubic volume weight, x 25/24 = 416666.66r grs. per Stecchini Egyptian cubic Ft. This figure reduced by the current standard value of water density per cu.in is 252.9 grs. instead of the old standard 252 grs. So, he got 1647.555028 cu.ins. Egyptian Ft., cube root of 11.81081797 ins. divided by 39.37 ins. modern Meter = .299995376 or so nearly 300 mm. he wouldn't know the difference in a million years. LOL! But it still wasn't the Egyptian Ft. of 12 ins. x 63/64 = 11.8125 ins. Funny how it worked out that way for both to be correct I think. And as I mentioned before, it wasn't because the Antient Egyptians could see into the future, but they could know the difference in density of Water at 4*C and the old Standard value of around 80*F. Which is the average climate temp during the harvest season enough to fix the value per cu.ins at 252 grs. exactly.
