* using stuff that was calculated using a slide rule... Just like the SR-71

The good news is that means that the US is a 2 percenter of countries that are "doing it right." I think that means the other 190 countries are practically cave men. Thank goodness there are no engineers in those other countries.

IIRC the Brits use miles for distance, stone for weight (14 lbs), pints for beer. But they are metric.

I have a 10 meter tape measure that I bought in Germany. I normally use it when working, waaaayyy easier.

10 of your SAE wrenches are already metric up to 15/16ths. Just need a few to fill in the gaps. With an adjustable metric spanner you almost have it made.

Some truth to that...don't know all the swaps, but 19mm and 3/4" are virtually the same. If memory serves, think a grand difference of 5/1000 of an inch.

If only it were that simple...

We use miles for road/travel distances and mph for speed. We measure fuel by the litre.... and cars are still able to be marketed with a miles per gallon (mpg) figure. Note we use a different gallon to the US one as well.

Metric weights are used in practically all areas (food stuffs, medical records etc) yet funds are still allowed as a standard measure in some food retail. Pound per square inch (PSI) is still recognised and widespread measure of pressure.. car tyres etc.

Beer and milk are the only liquids that can be sold in pints, everything else is in litres.

We measure letting and sales areas in building in square feet, yet build in metric, using Imperially dimensioned materials (such as bricks and lumber).

Land areas are more often referred by acre not hectare....yet field and land dims are metric.......

Couldn't make it up.

Pretty standard measuring tools here.... both used. The steel rule still has "West Germany" as country of origin...

5 milliinches?

We still sell weed as ounces and pounds. All other stuff is metric. Height is in cm, weight in Kg's, liquid in litres, and building materials are in mtr /cm / mm. Makes sh$t simple.

In the early 2000s, the US. Dep't of Transportation made a heartfelt run at the Metric system. Basically if you submitted a set of Design Plans (for a say a new road, highway or bridge) that were NOT in metric, you would not get paid.

It lasted a short time and then the program died as no-one could understand the metric units on the design prints and in meetings everyone just discussed the projects in miles, feet etc...sadly..for a moment I had hope.

Okay, I looked it up. Some wrench conversions SAE-Metric to jot down & put in your toolbox.

5/16 works for 8mm
3/8 works for 10mm
7/16 works for 11mm
1/2 works for 13mm
5/8 works for 16mm
11/16 works for 17mm
3/4 works for 19mm

Why keep both metric and sae when you can use one for both?
Covers all sizes from 1/4 to 3/4 :D

Steve, LOL! Yep..."covers" all sizes. Removing or tightening? Well, that's another thing...

Yes..it'll do both!
I think I've had it in my tool chest for over 20 years....never used it since trying it out when new. :)

Seems like a perfect too to round off those pesky corners on a bolt. :D

The worst thing about it is.....you are using a 1" socket to remove a 1/4" nut.

But no...it doesn't round off the corners because the round cylinders only place force on the flat sides of the nut.

I would not recommend it. :)

Did you get a second one for FREE ..... just paying the S&H :D?

No...it's a 'Universal Socket'
You only need one in your tool chest.

(Today's price would prob be huge.):)

Do NOT use it on a 10mm nut .... you have been duly warned!

I'm a flooring contractor and obviously deal with square footage constantly. Most of my materials these days are manufactured in metric measurements but I contract in square feet, and with carpet in square yards which just adds to the conversion bother. Too much math but I'm used to it by now. Everything would be so much simpler in metric. Divide into 10 vs 12? Duh

I think I've got one or two, but I haven't ever tried them. I think I got them when my dad died. They don't look like he'd ever used them either. One had smaller, denser pins which I think would make it work better.
