No inches in Egypt but there are inch equivalents:

11 x .363 = 3.993
8¼ x .363 = 2.99475
5½ x .363 = 1.9965

where .363 = OK tomb grid unit. IOW the difference between 11 of these units and 4 imperial inches is almost undetectable

perhaps 24825 x .363 = 9011.475 if you must have a figure.

>Like for instance "231"

Like for instance "331"

But then this is hardly the place to put your numerology to work.
