Miles (MPH) vs Kilometers (KPH)

The same math works for minuses, and -40 F happens to = -40C.

No, minus C.

Try converting -18C to 0F using the method proposed above.

temp in F = temp in C x 1.8+32 temp in C - temp in F-32 divided by 1.8

Works every time

Well, yeah, but I'm trying to find something SIMPLE that can be done in my head. And I'm lousy with numbers.

For me, SIMPLE is plugging the numbers into the converter in my PDA or into my HP programmable calculator.

I have to convert from metric to U.S. quite often and occasionally some arcane Japanese area measurements. Prior to converting to the metric system, area was measured in tsubo. 1 tsubo is the area covered by 2 tatami rice mats (which apparently were a standard size) so if you knew how many tsubo a room was, you knew how many mats you needed to cover the floor. 1 tsubo is 3.3 square meters, or .02815152 square feet. To keep this on-topic, Toyota's Georgetown assembly plant is roughly 28,150 tsubo.

My PDA is made of squiggly grey stuff and is inside my head with no buttons available that I can see except the ones on my shirt, and they don't work.

So do I. Temperature, capacity, distance, even area, easy. But one I don't ever have to do, unless I'm reading car articles, is the mpg to L/100km.

My wife came up with something simple, but I forgot it, and she's not home right now.

I do remember that:

When did Japan go metric?

Canada's a mish-mash. If it's regulated by the government, it's metric. If not, it's usually still Imperial.

Once you get past car speeds, distances between cities, temperature, and gas purchases, there's still a lot of Imperial around. In some cases, it's still almost 100% Imperial, such as lumber.

Once you get used to using a PDA, you're hooked (sounds like drugs). Besides appointments, birthdays, phone numbers (I have around 2,500 stored), I use the calculator and note pad quite often.

I'm OK with miles to kilometers, liters to quarts & gallons, and lux to footcandles but that's the only thing remotely easy for me. I need a calclator for everything else.

I know what the various size sockets and wrenches look like but I couldn't tell you the fractional equivalent of a metric socket.

Good question! I have no idea although I seem to remember everything being metric when I visited in 1970. I'll ask around.

It would not bother me if the U.S. went metric even though I'll be one of those old farts who can't figure out the conversions. Of course, the U.S. would have to get rid of the stuff that drives me crazy like:

rods for canoe portages in the Boundary Waters Canoe Area Wilderness bolts for fabric knots for aircraft and marine nautical mile ounces, cups, pints, quarts, teaspoons, tablespoons in cooking fathoms and leagues for water depth board-feet for lumber

I think your finger got off its leash on the way to the calculator. 3.3m^2 is slightly under 4 square feet. So that means a tatami mat is the equivalent of 2ft on a side.

Know what I find fascinating? That Russia's traditional "line" was precisely 0.1 inch. I used to wonder why you'd find so many Russian rifles with barrels exactly 20" long, until I discovered that 200 "lini" was exactly 20".

See here:

I don't think it makes any difference at all what system is used. It's like speaking a different language. Aren't you bilingual English/Japanese? No language is impossible to learn.

My ties to Imperial are threefold:

Canada should have remained Imperial, if only for its inextricable ties to the US. Of course, those ties were Trudeau's impetus for Metric in the first place. That communist idiot absolutely *hated* the US, and everything it stood for.

It's now meters up here.

We still use those, except for retail reportage on the TV and in newspapers.

The airline industry is still Imperial. Ceilings are still reported in feet. Speeds in miles.

We still use that. Nobody wife or I know uses metric for cooking.

Don't know what's used here. A boat for me is something gravy comes in.

Same here. Lumber is 100% Imperial. Houses are advertised in square feet.

I just did some poking around here at home to see what things

Castrol GTX motor oil: 4.4L (.97 Imperial gallon) This is odd. Until very recently, it was sold in bottles of 4L, or 1 US gal, 7oz. The 4L kind was better for me, since my engine takes 1gal of oil, and I could just dump the whole thing in. Now I have to drain some off.

Genuine Toyota coolant: 3.7L (.98 US gal. I'm sure it's really 1 gal)

Bag of flour: 1kg (2.2 lbs, used to be 2lbs exact) Del Monte peaches in a clear jar: 540mL (19oz, same as when I was a kid) Campbell's condensed soup: 284mL (10 oz, same as always) Campbell's ready-made soup: 540mL (19oz) Aluminum foil: 25ft Saran wrap: 500ft Butter: 454g (exactly one pound) Ziploc bags: 25.4cm x 35.5cm (10" x 14") Box of crackers: 200g (7oz) Bag of cookies: 350g (12.3 oz) Spray cans of paint and primer: 340g (12oz)

Most of this stuff seems to have actually been made in Imperial, then converted for labeling purposes. What a joke.

I like that - logical thinking!

I speak English and Japanese although my Japanese is a little mixed up. My every day vocabulary in Japanese is probably about that of a 5th grader but I can name every part in a car in Japanese. I can read the 2 easy (50 characters each) out of the 3 alphabet systems which is enough to read Pokemon cards and comic books.

The only inherent advantage I can see to metric is the ease of multiplying and dividing by 10 and since the rest of the world is metric, some conformity.

I'm not a fan of over-legislation either.

Your wife cooks? (just joking honey)

Japanese food packages list grams, cc's liters.

To me, a boat is something a semi-wealthy to wealthy gentleman or his wife or mistress drives to the country club.

A system that teaches square meters and then does business in square feet sounds messed up to me!

Then again, I read that there is a big black market on toilets smuggled in from Canada because they still flush with enough water to make everything go down in 1 shot.

It's MY finger that got off its leash! BAD finger, BAD finger. I hit the square yard button instead of the square foot one.

And I had the conceit that one day I'd try to learn Japanese and Russian...

I just open cans and heat stuff up. It's all I'm allowed to do. SHE's the chef in the family.

Ours list grams, mL, and ounces about 50% of the time.

It is. Takes time to teach the kids real life. School is not real life.

NOBODY knows how big their house is in square meters.

You buy a property, you buy it in acres. I go by properties being severed off, and I see zoning signs like 0.404ha, 61m frontage (actual sign two miles from my place). That's an acre with 200ft frontage.

There's another one where a guy wants to build a garage 29ft west of his house (I think any closer would take him too close to the property line). The sign says 8.84m.

In construction and land use, everybody talks Imperial, but when it comes to conforming to the regulations, the calculator comes out...

Then there's the road grid. When they surveyed my area over a century ago, they made it a one mile by two mile grid. Metric really screwed that up. Some enterprises simply ignore metric entirely, and paint stuff on their trailers like "4 miles north of Hwy X". That means four concession rods north of the highway.

Metric up here is slightly schizo.

Yes! The 1 gal/flush ones are out there, but nobody wants them.

An Oldsmobile is european?

nope i think... or maybe i dont know a way how to switch between those modes? can anyone tell me how to do that? p.s. how do you mean - dual? its one electronic display with possibilities to display ODO (miles) => Trip A => Trip B...

For me, simple is pressing the button marked MPH/KmH. This converts all of the displays -- except the odometer -- to metric or SAE.

You haven't been following the thread, have you? In the hypothetical situation being discussed, there is no machinery available.

Yes, I know. If I can't get what I need by pressing a button, the odds are good I don't need the information. Simple is pressing the button. If I gotta do the math, it aint simple anymore.

That's the Odometer, it measures distance. The Speedometer is the one that tells how fast you are going. The Odometer is goinig to be in the units of the market your car was designed for. The Speedometer is also going to be in the units of the market the car was designed for. There are two sets of numbers on the speedometer, one is large and the other is small. The small numbers are Kilometers if the large numbers are Miles, and vice versa.

versa.

thanx! thats quite clear to me... but the real question is - is those modes chanchable? and if so - then how? i mean can i change odometter from miles to kilometers? and yes i have speedometer with large circle with MPH and a small one with KPH - and here the question is - is thats possible to change that rim to only one with KPH and where can i get one? thanx again!

A European wrecking yard ("breakers" yard). Get a whole speedometer/odometer assembly.

Canadian speedometers have km/h as the main display with miles inside of that.
