Selecting Nails
Pennies and Inches
In Great Britain in the 1400s, you could buy 100 medium-size nails for 8 pennies. It didn't take long for inflation to destroy that designation, but we use the term penny to this day to size nails. The abbreviation 'd' for penny is derived from denarius, a small, silver Roman coin used in Britain that, from early times, equated with a penny.
Inch equivalent of nails sizes:
3d=1 1/4'
4d=1 1/2'
6d=2'
7d=2 1/4'
8d=2 1/2'
10d=3'
12d=3 1/4'
16d=3 1/2'
20d=4'------------------------------------------- posted 7:25 AM :: reference link ::
