Imperial vs Metric

the button on the MFD only toggles the speedo. You can't change the other readouts to Imperial from metric. Not even the OAT readout on the MFD.

 

I'm from Canada but live in Japan. I'm used to MPG (imperial) but from hanging out here at Priuschat, eveything gets benchmarked at about 50 MPG (US). My display gives me kms/litre and 21.2 kms/litre means I am getting 50 MPG (US) or 60 MPG (imperial)

So its not confusing at all, right?

what you want is a US model and then the speedo toggles to metric and everything else is imperial.

 

Not imperial, US. US gallons are different from Imperial gallons.

 

Uh-oh here we go again!

Remember: 1 U.S. gallon is approx 3.78 litres

1 Imperial gallon ("Canadian" gallon or a gallon everywhere but the U.S.) is approx 4.54 litres.

Most countries that have adopted the S.I. or "metric" system rate fuel economy in L/100km or litres used per 100km: less is better.

Having lived most of my life in Utah, I find it somewhat ironic and very amusing that locals here refer to MPG but *not* to the MPG I grew up with. Their "gallon" is NOT my "gallon" and so forth.

And folks wonder why that Air Canada Boeing 767 ran out of Jet-A between Toronto and Calgary. They were at cruising altitude over Red Lake Ontario when every last drop of Jet-A was finally consummed, and the 767 became a glider that finally made a safe landing in Gimli, Manitoba.

The Boeing was allowed to take off with dead fuel gages. The ground crew had to convert the litres on the dispensing equipment to gallons. They made huge errors in the conversion and put in less than half the fuel needed.

BTW: I don't understand why the temp display can't be changed by itself. My 2000 GMC Sierra SLT has the temp/compass display in the rear view mirror, and all you had to do was fiddle with the mirror buttons a bit and toggle between F and C.

 

It seems to me that several folks who drive Prius' in Japan mention that their vehicle displays km/l, not l/100km as ours does in Canada. Am I correct in this?

 

Gary:

That's correct: km per litre.

I was told by my local Prius tech that when I do move back to Utah, it would be straightforward to use a THHT to change the display to U.S. Primary, which will display MPH by default, MPG (U.S. gallon) and temps in degrees fahrenheit.

your right on the fuel mileage being in USgallon but everything else is imperial. temp mileage's etc.

 

Frank:

That's a good point.

I've never understood why there was a difference just for liquid volume. Degrees fahrenheit are the same all over the world, a mile is a mile (Ok, a smarty-pants would also throw in Nautical Miles just for lively debate), but a gallon isn't always a "gallon."

Jay

 

why are nautical miles used in avaition? Other than for float operations. Degrees minutes seconds. Good to know that wasn't used in automotive.

Geez I don't know. It's weird, "nautical" miles for something flying through the air 35,000 ft over any water.

It would be like having an altimeter on a boat ...

I enjoy nautical miles 'cause a nm. is generally considered to be 6000' so is easier to work with than 5280'. :lol:
Hey, Jayman, I did have an altimeter in my boat.... it was the GPS alt. readout.... often reached the oxygen- reduced atmosphere at 40 feet off the coast of Oregon ukeleft:
