Very interesting!

In the biggest overhaul of the international system of units since 1875, countries have voted to redefine four basic units of measurement the ampere, the kilogram, the kelvin and the mole.

Largest overhaul of scientific units since 1875 wins approval

Their usefulness is beyond measure.

Dumbest thing the United States ever did was not adopt the Metric system. Well, one of the dumbest, anyway.

While it's clearly superior system it's completely impractical to switch. Let's start with the construction industry and a similar existing issue, if you have a very old house it may have rough cut 2*4's which are actually a 2*4. Modern "2*4's" are nominal dimensions and are actually 1.5*3.5 in. When you are working on existing walls in a house like this you would either have to special order true 2*4's or fur out every single regular one you install. The same issue would exist if you switched to logical metric dimensions but this would apply to just about every structure in the US. Deepening on their size they would either have to be cut to size or furred out.


Even more importantly the structural component of walls, ceiling, roofs and floors are built with 16 inch centers. When you take 4*8 sheet of drywall, plywood or whatever this perfectly fits with the edges sitting on half of your structural member. When for example you go to put a roof in you can lay most of the sheets of plywood one after the other, you only need to cut the ends and some other pieces.


This of course is also done with metric sized material which is not an issue for new construction, it's the 100's of millions of structures already built using standard material that are the issue.


To switch to the metric sytem you have to make a choice.


  • Fully switch to metric using logical dimensions.This would result in a huge amount of wasted material and increased labor costs when working on existing structures.
  • Provide both sized materials. That's going to get expensive for both production, transportation, storage etc. Furthermore the contractor who has worked with standard material his/her entire life is going to walk right by the metric material to the standard material. This would just be a giant boondoggle.
  • You could label standard sized material in odd metric dimensions but that is kind of pointless, it's still a 4*8 sheet of plywood.
As you can see not a whole lot of good options, it's not just the construction industry either. There is going to be a lot of industries where such switch is going to be a huge issue.

We will get there just a "liter" bit at a time.

Standard diameter of a 2 liter soda bottle is 101.5mm OR 3.996 inches, this allows you to precisely fit 12*12 on standard 48" pallet. That pallet can be fit two across in a tractor trailer that will have a minimum 99" inside width but likely a few inches wider for some more wiggle room. The volume of the soda bottle is not enormously relevant, the diameter certainly is. If you went and measured most of the products you purchase what you'll find is they will have dimensions designed to fit on that pallet which is standard sized.

Which is of course different from the 80 by 120 cm EUR pallet because nothing can make sense. And neither US nor Euro pallets fit nicely in an ISO standard shipping container, what with it having an internal width of 7ft 10 inches (or 2.34m, if you prefer).

Standards are great, there are so many to choose from!
