Need a ruler...decimalinch
I'm trying to measure my frame to be sure it's not tweaked. All the factory measurements are in inches... but decimal inches like 8.15 inches.
Where can I purchase a ruler/ tape measure that can do that? 
I have never seen such a ruler. Just get a decimal equivalent chart and convert yourself.

here's a conversion chart you can print and a calculator

Look at Ben Meadows.com (see Link below). In forestry we use these kind of tapes all the time. Some are in inches and some are in 10th's. On the back side of the tape it will have measurements for the diameter. You can measure around the tree (circumference) and just read from the tape and it does the math for you to get the diameter without having to cut the tree, (they'll get cut later).

Just use your normal ruler... one inch equals 100/100th's...so a quarter of a inch would be .25, a half an inch .50, and three quarters would be .75 etc. Breaking it down smaller an eight of an inch would be twelve and a half hundredths, a 16th would be 6 and a quarter hundredths.

I use a rule thats designated in decimal inches every day. Starrett, Brown and sharpe and Mitutoyo make them...to name a few. Pricey little things though.

Decimal ruler
There are two types of decimal rulers. One is used by surveyors, the other by machinists/engineers. The survey ruler is divided into tenths of a foot, not inches. The engineer ruler is divided into tenths of an inch and parallels the measurements on the leaf thickness gauge and the micrometer. The one I use is from Lufkin and can be found on their website. Mine is a 12' tape and cost $8.80 + SHT. There are other sources, but this was the most reasonable price I found.

Just convert it yourself. Example 3/8'' = top # divided by bottom # =
3 divided by 8 = .375''. 
Conversion
The ruler has decimal inches along one side and fractional inches on the other side. You just look at the mark directly across from what you want to convert. No room for error, no transposed figures.

Or we could just get smart and convert to the metric system like every other country in the world, and like we should have done fifty years ago. :thumbup:

Temperature and speeds are not too bad....but this litres/100 km thing instead of miles/gallon ......makes no sense to me. 
Stanley part number 33272.

. 03125 is 1/32. Times five is the nearest to .15.. This is just a smidgen over at . 15625".. So it's 5/32"..
I always divided 1 by 32 which gives me a pretty accurate number. Anything tighter and your looking at 64 th. Hope that helps.
