Do you think this would be handy?

I was looking at the back of my digital calipers when I noticed ...

Whitworth? Who tf needs this chart?

People working on old British cars?  My thread pitch gauge is a metric whitworth combo. I usually only work in metric at this point, but metric and SAE would probably be more useful.

The sad thing is that those aren’t whitworth threads listed, those are UNC.

Thanks, China.

my copy of machinery’s handbook, 17th ed (1964) has pages for converting liquid measures such as tun, pipe, puncheons, tierces, and hogsheads.

1 hogshead is approx 63 gallons, if that was keeping you up at night or something.

I actually knew how many gallons are in a  hogshead. Strangely enough.

Are you for real? Do guns and cameras really use whitworth?

Yeah I’m shipping 1/4 Tuns of liquid all the time.

Due to the S impsons? That’s why I know it.

Nah I had some binder in high sc hool with a bunch of conversions liste d in in and that one made me laugh so it stuck,

I’m pretty sure 1/2” is 13 TPI for UNC, as opposed to 12 above, I think 9/16” is 12 TPI for UNC.

Had to Google SAE, being only famili ar with imperial and metric.

Turns out that SAE is a system of parts and tools made to something called USCS units, equally new to me .

Could be. 5/8-11 and 1-8 are common, I don’t deal much with >1/2" to know that part of the table off-hand.

When I worked in manufacturing we used 1/2-13 and 3/8-16 for most of the fixtures we designed/built,  which always amused me because the parts we were machining or assembling in said fixtures were designed in metric. :)

SAE is Standard American- English. Otherwise known as inches and feet . Otherwise known as freedom units.

I remember tools in fractions of an inch but they were always called Imperial! SAE tools use different fractions of an inch or something. Also, you still come across (well, I do...) tools with both BS and Whitworth sizes.

Imperial and SAE are functionally the same. I've always heard the names used interchangeably.

I've never into BS or Whitworth, but I've never worked on any British cars :)

You need W hitworth thread pitches often?

Yeah I figured you’d find it useful.

actually that is a bad attempt at labeling by what I assume is a chinese made? caliper, the attendant info is actually just american std info, having really nothing to do with actual whitworth threads, as i understand it the whitworth threads were abandoned in the late 60's early 70's in favor of the american std. I started in the machine shop business in 74 and cut thousands of threads over the  years and never had to encounter a situation where whitworth came up even though we were in the business of repairing and restoring older equipment. as one of the older guys told me the main difference was the angle of the thread form, the american std is 60 degrees and the whitworth was 55, so we may or may not have encountered some over the years and depending on the tolerance an american bolt fit in a whitworth threaded hole and no one knew any diff. or just assumed it was buggered and chased it with a tap

Well it’s good to know that these aren’t W hitworth the american std info might actually be useful to me
