Metric vs Imperial System

[Farm Boy]

Dude. Everything gets fixed in both. The crescent wrench isn't the metric wrench anymore.

Base ten is nice for conversions you don't do all the time, but not everyone has a particular fetish for it?

I suppose sometimes realizing a nut is metric and switching wrenches is a good indicator that the piece is likely to break before the others if it's in a wear role.

Err...there is no reason you could not use metric in multiples of sixty as well. If you go 120 kph per hour, you cover 2 km each minute. If you try to do the math with the equivalent 75 mph, it gets much more complicated. There is no useful multiple of 60 in the definition of a mile.

...Is there ia useful multiple of 120 in the definition of a kilometer? 1 min = 1 mile is less complicated than 1 min = 2km, as well.

So you are in favor of carrying two sets of wrenches for all eternity instead of doing something to fix the problem?

Base ten is convenient, but the real advantage of metric is that there is a base.

Obviously not, neither mile of kilometer are in any useful way related to 60.

The point was that 1 min = 2 km is less complicated than 1 min = 1.25 miles

Obviously...1 min = 1 mile is less complicated still. This is coming from someone who can only dream of 20 mins = 20 miles, mind; y'all live in the sticks.

I still once in a blue moon use an old square nut because we still have them and they still work. I'm not bothered by having an extra set of wrenches, rather than throw them away because somebody with a base 10 fetish doesn't like them. They're the sort of person that will eventually come up with some simplifying solution and then there will be three sets of wrenches to lug around.

Yes, while that is true, it is easier for me to figure out in my head if I use imperial measurements as a multiple of sixty can be directly and easily converted into time. 60 MPH = 60 minutes directly and easily. No heavy calculation required. Whereas with metric, I have base ten to convert to a time base. How many kilometres do I cover in one minute? Multiply or divide a fractional measurement by 60 in my head... Arrrgh. It's fine if I'm working with a full hour, but if I want to figure out when I will be somewhere and have 20 km to drive, the math is just irritating. But if I'm using imperial and I'm 20 miles away, I know I'll be at your house in 20 minutes. No migraine.

It's just the way my brain works. YMMV (no pun intended).

Ah, usually for intermediate distances "hours" are not used here. At least I don't think so. It's usually used in terms of cities connected by highways. So if it's around 200km you say 2 hours. It's not exact, and you never have to think about how many minutes are how many km or whatever. And sometimes you'll hear "six and a half hours", but that's easy to figure out, that's just 650km. Getting more specific like that in this context isn't required, because if somebody is driving from Ottawa to Toronto you can't predict your arrival any better than 30 min chunks anyway.

I agree that you'll just use whatever system you grew up with and are used to, probably, though

It was the mistake of the Obama administration to introduce Common Core math to K-12 without AP Number Theory classes in the high schools.

AP Number Theory course will be nice because it won't the requirement but a possible choice for the honored students. It's a math class in the university that specifically studies number properties in different bases mainly binary, octal, hexadecimal for computer science, also odd, even, prime numbers with the certain combinations. When I first saw those Common Core materials and the unit conversion lessons, I was confused too, then had to find all the answers how to efficiently deal with them from the skills of the number theory strength.

Conversions between Metric and Imperial systems will be extremely hard without the proper understanding of the number properties.

General public don't talk about AP European History or AP Art Studio on the daily basis, these are the knowledge foundations that can be reached not far away from the busiest hallways of the local high schools.

Obviously not, neither mile of kilometer are in any useful way related to 60.

The kilometer measurements in the dozenal base can handle the clock math really well, the major problem is that our world doesn't have a default math base that is friendly to the clock.

10 is a wild card in the math number base theory -
