nonsense?
I once had an imperial ruler that divided inches into tenths. I am wondering what that would be used for, maybe writing in decimals?
Well.... The Murican inch may be 25.4 mm (or 25.39whatever). The DANISH inch, however, is 26 mm. Just thought I'd point that out. I actually have a tape measurer that measures in cm and Danish inches.
Ya know. I think there's a reason the world has converted to the metric system. Now we just need the US, Liberia, and Myanmar to catch up.

I still have one. It's an old drafting ruler. The first inch is divided into 100ths.

Most of my rulers include graduations of tenths of an inch so I researched the topic and found the following.I once had an imperial ruler that divided inches into tenths. I am wondering what that would be used for, maybe writing in decimals?
Decimal rulers can be based on both the Imperial system and the Metric system.
Decimal rulers using inches normally have graduations of 0.1" and 0.01".
Is it not true that NASA put men on the moon using decimals of an inch?

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.I have a 12" stainless steel rule
