What would be the point of not nuking this OS X?
How portable? How precise?
The foot, as I explicitly referenced in my reply, has a definition that can be easily referenced to increase its precision: a ruler.
Error of several inches would fall into the realm of “about as long”.
What conversions are a pain under sae measurements?
Very precise so when you measure something you get it’s length so that it’s length can be compared to other objects. And portable so that other people who don’t have access to your specific ruler can fashion a ruler of their own that will give measurements that are the same length as yours
An error of several inches in any real world use case for a measurement system could very well end in disasted.
And from inches to foot, foot to yard and foot to mile.
Metric is easier to remember conversations, easier to use, and is way more portable and precise
who the heck is out here fashioning their own rulers. can you imagine that for metric? “jim, you finish making that cut yet?” “no. i need to zero the chronograph so i can make a meter stick.” all measurement systems have inexact portable standards and i’d say it’s not something metric handles better than sae.
there are 12 inches in a foot, three feet in a yard and 5280 feet in a mile. you can use the little star button under this post to “save” it for later in case you forget and need to refer back. i’m not trying to be passive aggressive, i used to have to look up the foot to mile conversion a bunch before i did a stint of surveying.
can you explain what you mean when you say that metric is more portable or precise? what measurements are more precise or more easily made to their appropriate degree of precision with the metric system?
Ok now do inches to miles, what about distance bigger then those measured in miles what now? Try miles to yards without looking it up what about measurement smaller than a 1/16 of an inch? What are we just gunna start using even smaller fractions? 1/1000 of an inch? or would it be some arbitrary unit called a speckle or something that’s 18/29382 of an inch?
And no one makes their one rulers except physics labs, and maybe ruler manufacturers.
Metric has more precision due to its definition based on a universal constant. Imperial could have that to but it doesn’t shake it’s weird conversions. Yes they are easy if you are doing surveying work but there’s a reason scientists use metric. It’s much easier to check and use especially when dealing with scientific notation.
Also fun trick for feet to miles is 5-tomatoes = 5 two 8 Os
Now let’s do kilometers Oh wait it’s literally just it’s name 1000 meters

well, if youre’ drilling holes, 32s are pretty common, as are 64ths. my copy of machinery’s handbook uses mils, which are thousandths of an inch just like you said.
if no one makes their own rulers except labs and ruler factories then why is making rulers important for portability, something your said was important?
metric doesn’t have any more precision because of it’s definition based on a universal constant. over time as new constants arose, plenty of non metric systems adapted to them and changed to include their enhanced precision. the nautical mile is a great example of this! metric systems have also switched universal constants over time to become more and more precise, just like everything else.
a measuring system needs easy conversions most when the people using it can’t just look at the thing being measured and say “that’s not five hogsheads you imbecile! that’s a tun!” metric’s easy conversions are really good for stuff like voltage and the distance from the earth to the moon, but should everything be powers of ten? i don’t know. it certainly would remove pressure from people to learn how to easily divide by other numbers or comprehend fractions.
i’m not sure that’s a good thing.
