Truck ton ratings....

That would probably be easier to remember than asking: "Is it a 453.592 kilogram?". To me the metric system never has and never will make any sense at all.

Try this: Add 5.3 centimeters and 3.2 centimeters. Quickly now! Okay, now divide 12 centimeters by 3.

If you can't do both in your head almost instantly, go back to 5th grade.


Now, add 5/16 and 3/32 inches. Quickly now! Now divide 7/8 inches by three.





There is a vast difference between, "makes sense", and, "I'm used to it". Too many people don't know the difference.

Please describe the oh-so-common 2X4X8 building stud using the metric system...?

What they commonly use is 45x90.

Say, if you were going to build a stacked beam with 2x4s, how many would you need to get a 12" beam?

If you were going to build a stacked beam with 45x90s, how many would you need to get a 315mm beam (about the same as 12")?


(By the way, a 45x90 measures.... 45mm by 90mm. Odd.)

I have never quite understood why people continue to use the antiquated system of rating trucks by half ton, three quarter ton, one ton, etc. This would include both light trucks and medium duties...indeed, the last medium duty truck I drove for a living was termed a 3 ton truck by the old system although it was rated by the factory for over 30,000 GVWR and the base chassis weighed only about 14,000 pounds. I say it is time to update the ton ratings and not just go by the classes 1 thru 8.

I thought the term, 1/2, 3/4, and 1 ton originally referred to payload capacity? and has nothing to do with GVWR...As mentioned, rating in this way just stuck...its what people remember, even though capacities have increase significantly over the years....Why would you not end up with the same issue down the road. In general, each remodel bring a bit more capability, so what was a class 1 today might be a class 2 in 40 years....

Back when I worked in the furniture industry all drawings were in English measurements...
Later in the 80's and 90's as manufacturers started utilizing European machines of course all of their measurements were in Metric...
I spent lots of hours converting shop drawings and training operators...
We would have a BS measurement (between shoulders) of say 40-1/2"...
If the double end tenoner was set to that and the operator got off just a smidgen we would say 40-1/2" heavy or 40-1/2" light...
New assembly and construction methods utilize 32 mm and it is much simpler and standardizes the machining and assembly...
This assembly and construction method has been around a long time but it is hard to change...
