american v. metric quiry
 

when a tool is listed as SAE what does that stand for? i always though the A= american & the S= standard but am at a loss for the E. any help? i thought it had to do with inches and fraction there of. you never see it on a metric tool.

a google search says its society of automotive engineers.

google is correct

GIYF

XXX

Sigma Alpha Epsilon



Society of Automotive Engineers.

So what standard did they (or do they) use in England for feet and inches?

Metric is metric around the world, but somehow I dont think the limeys used SAE anything...

Didn't they refer to that as "Imperial", like an Imperial gallon, or an Imperial ounce.

I think the American system you speak of is called "Imperial" and was originated in the UK.

I've got the shift knob off a '67 E-type that I'm going to mount as the knob for my chopper. It's got crummy Whitworth threads from hell...going to have to drill and tap it.

The US required SAE threads on imports beginning in the early 1960's. I'd be surprised if your shift knob from a 67 e-type is Whitworth, could be wrong however. Check with moss motors in Goleta, CA
