Decimal Inch versus Decimal Foot

[rgsparber]

I was looking at various steel rulers and came across an odd thing.

Decimal Foot:

I have always preferred my decimal inch ruler which is 6 inches long. But I noticed I can buy decimal tape measures that are 25 feet long.

Sounds like a nice addition to my shop. But now it appears these rules are decimal FEET, not INCHES. That means there are 10 decimal inches in a foot. Wow! So on that rule a tenth of a decimal inch is not the same as a tenth of a (common) inch. Anyone else see this or am I just confused?
