Leather thickness - units

[jakc3]

Hello,

I got in touch with a certain french tannery and they sent me the information about their articles. However I haven't yet seen such units for leather thickness or at least not with such numbers.

Could someone please enlighten me on how these would convert to millimeters:

15/17

20/22

26/28

 

Many thanks,

If the numbers you show refer to the weight of leather in ounces, the following should help.

I think my math is correct.  15/17 is 15/64 to 17/64 of an inch or 5.95 to 6.74mm

                                            20/22 is 20/64 to 22/64 of an inch or 7.93 to 8.73mm

                                            26/28 is 26/64 to 28/64 of an inch or 10.31 to 11.11mm

Those numbers are awfully thick to be ounces.   I suspect they may be mm without the decimal.   So maybe 1.5 to 1.7mm.  2 to 2.2mm.   Etc.  Those sound like more usual leather thicknesses.

Thank you very much, it is indeed in mm without decimals.
