No. Why would multi-digit decimals be too hard, when I'm the one favoring metric and it's ease of decimals? I use imperial daily as well. But metric is just simpler to get more accurate measurements without having to resort to multiple decimal places.
yeah, i really think i'd need to see an example of what your point is because if you do a calculation in metric.. say 25mm ÷ 8, you end up with 3.125mm ..
if you do 25" ÷ 8, you end up with 3.125"... it's the same exact thing, right? how are you thinking metric makes calculations end up with single decimal digits whereas imperial has long decimals?
(and, btw, in that example, the imperial version can also be written as 3-1/8" ..which also, conveniently, has a mark on your ruler for you to tick)
can you clarify this single decimal thing?
[edit] unless you mean something like
25cm ÷ 8 = 3.125cm
but that can also be said 31.25mm..
or- 25m ÷ 8 = 3.125m
but that can also be written/spoken as 3125mm
so there are less decimals being used in metric
?
if so, i don't think i'm quite backing this notion.. i mean, the math is the same with both. (actually, the math is the exact same but then, with the metric example, you're doing
additional math on it in order to show less numbers after a decimal point.)

Umm...okay. So, we should keep a variety of non-related measurements (whatever you feel that day to an inch, 12 inches to a foot, 3 feet to a yard, 5280 feet to a mile) instead of using a system in which all the relations are the same, so that you have more standard tolerance within a single inch. Copy that.
no, we should have a unified (coherent) system much like metric (though modernized to include units for computers etc).. i think if you re-read what i've written, i've given examples of when imperial is better and i've also given examples of when metric is better.. i've never made the declaration that one is better than the other because neither one is better than the other.. they both have advantages and they both have disadvantages.. one of the advantages of metric is that it's a coherent system.. this trait should be adopted in a new universal system.
I get it. I use inches in all of my CAD and 3D work (and often use mm as well), but to say that inches are better...eh, don't agree.
inches are better.. sometimes.
cm are better.. sometimes.
if one was superior to the other then it would be better in all or most scenarios.. this simply isn't the case.. neither is better. (repeating myself, i know... but..)
And base 12 is somehow better than base 10? So, instead of 1, 10, 100, 1000, 10000...it's better to....1, 12, 144, 1728, 20736?
hmm.. yeah, i don't think you're seeing base12 yet.. in base12, there are two new digits for the numbers 10 & 11..
a few have been proposed such as ᘔ for what's known as 10 today and Ɛ instead of 11..
the numbers you've written as 1,12,144,1728 in the decimal system look like 1,10,100,1000 in the duodecimal system..
here, watch this:
and read this:
https://en.wikipedia.org/wiki/Duodecimal
....
and my point of bringing this into the discussion is that, if we were to adopt the duodecimal system (and seriously, if it were an easy switch and mathematicians only had to vote yes_or_no on the matter, an overwhelming majority would vote yes.. or even 'yes please!' : ) ..not because it would necessarily make their more complex problems any easier.. more because it would make math easier for everyone else.)
...
if it were adopted and we then made a new measuring system which worked like metric except now in base12, people would then realize "oh, i see now.. that's how feet&inches worked in the old imperial system.. neat."
like- base12 isn't a new concept.. it was almost implemented at points until those darn french had to come in and screw everything up.. instead of changing the numbering system to adapt and make sense to what was happening with the measuring units, they changed to unit system to adapt to the decimal system.. this was, quite possibly, one of the biggest blunders of all time..
if they would have done it the other way around and i was now proposing "hey, let's switch to a decimal system!", it would be a ridiculous idea to mathematicians and everybody else (like yourself) because it would be a disadvantage to duodecimal.
it is an incredibly tough position to be in if you're trying to argue a decimal system is better than duodecimal.. incredibly tough. (assuming involved parties have an equal understanding of both.)
Intertesting point you bring up. Most blueprints, if using imperial, use inches for small measurements, and feet and inches for larger ones. In fact, I have only very rarely seen a blueprint which says that a room is 217 inches wide. Nor, have I seen one saying that a wall is .4167' thick. They have the room being 18' 1" wide and the wall being 5" thick. Maybe I've been looking at the wrong blueprints, though.
that example was metric blueprints.
in imperial, one wouldn't (doesn't) stick to inches.. it's perfectly acceptable to dimension 18' 1 and 5" in the same document.
that's known as
feet and inches
another standard is
fractional inches (66 5/8 instead of 5' 6 5/8)
or you can use decimal inches as a standard (66.625")
not sure what CAD application you use but in Rhino, these three are your standard options without customizing:
i use fractional inches for most of my dimensions/shop drawings.. when working on larger scales, i use feet&inches..
typically, i'll never write a dim with more than ~150".. i'll always go to feet&inches at or around that point.
Of course. It just matters how clean you want your documents to be, and how easily it is to switch from one scale to another. For instance, in the example above, to switch from 217 inches to feet, you have to do math to get 18' 1". Most people can picture 50', but will have to think a little bit in their head to picture 600 inches. Instead, you can list the rom as 5.51m, 551cm, 5510mm. No math involved. THAT is why metric tends to be easier...no math to switch scales.
idk, it would be very uncommon to see something dimensioned or spoken of as 600 inches long. (fwiw)
likewise, it would be uncommon to see something dimensioned as 55mm and 5.51m in the same document.
but yes, i get your point.. if you were told something was 600 inches tall then it wouldn't be easy to imagine that length in your head.. you would prefer it to be in a different unit so yes, you'd have to divide by 12 in order to arrive at a better unit for visualizing something 50 feet long.
What modern system do you think could replace the simple moving of a decimal to change scale? Ooh...let's go to base7!
the duodecimal system
(i mean, any base system would work the same in these regards.. it's not only 10 that allows for this to happen.. the way we were taught and having the decimal system hammered into our brains since before we could walk or talk, we think 10 is magic but that's just because of the way we were taught. (poorly in many cases)
