It's certainly not unusual to have rules calibrated 10ths of an inch. I have a 12" stainless steel rule date stamped 1943 that has four scales.

1. 16ths - 32nds - 64ths.
2. 12ths - 24ths - 48ths.
3. 10ths - 20ths - 50ths.
4. cms - mm - 1/2mm.

Those combinations on one rule are a bit unusual I think.

I also have a 12" Chesterman No.412D rule dated 1961. It also has four scales one of which is 12ths - 24ths - 48ths - 96ths on an inch. It is also marked "Standard at 68F"!

Yes mine was steel as well and had only tenths. I know that scales often have the decimal inches but I figured they just needed to fill up one last side.

For pcb design a electronic calliper metric and imperial is absolutely vital.
Its also handy for conversion between them.
Measure using metric then press mm/inch button and it converts.

I might be wrong, but I always thought that imperial rulers graduated in 10ths were machinist rulers.
As in take a tenth of an inch off here, Or we milled your cylinder head 5 thousandths..
