    Hi All,

    I have noted how the subject switch button on the Prius dash provides the option of showing
    speed in miles-per-hour or kilometers-per-hour. That is fine for the folks on the metric
    system (which the US should be too!), but it seems illogical that while the speed can be
    shown in kph, the fuel consumption metric remains in MPG. One would have thought that
    Toyota would have linked the display to show relevant fuel consumption in kilometers/liter, liters per 100km, or a similar measure rather than staying in MPG.

    Any thoughts on why they didn't link the two measurement systems?

    Cheers, Ron.

    If I remember correctly, there's a setting in the MFD menus to change that over? Can anyone back me up on this?

    Don't think so...

    There should be, if Toyota built any flexibility into their MFD programming. Quite simply, ltrs/100km = 235.22/MPG. A single programming line, I should imagine, measured off one or the other parameter. Since the Japanese use the metric sytem, along with practically everyone else on the planet (the USA, Burma and Liberia are the only holdouts!), MPG is probably a derivative.

    Cheers, Ron.

    Well here in Canada, where everything is supposed to be metric, the Prius display is definately in Litres/100km and it can't be changed... not without getting the computer software updated. The process isn 't simple since it also has different displays for the MFD when you are on the consumption graph...

    Well, this certainly isn't as annoying as microsoft publisher assuming that Canadians us A4 paper and measure our desktop publishing in cm.. versus inches...

    FYI: Canadians measure things this way:
    Fuel, Milk, softdrinks: Litres.
    Drinks at restaurants: fluid ounces.
    Alcohol in restuarants: fluid ounces.
    Alcohol in liquor stores: milli-litres (though we actually call them on by the ounces).
    Meat in receipes and restaurants: Lbs, ounces...
    Meat at the deli counter: 100 grams.
    Height: feet and inches.
    Distance travelled and speed: kilometres, km/hr
    Size of lots: feet.
    Temperature for weather: Celcius.
    Temperature for cooking: Fahrenheit
    Aviation altitude: feet
    Height of the CN tower: metres
    Nuts and bolts: imperial AND metric... (if it came from europe, it's metric)
    Engineering: both, in the most inconvient way... torque in mm-lbs f anyone?

    So we are used to dealing with both...

    Anyone notice that the ODO stays in kms or miles? When importing a car, you must have the ODO converted or clearly labeled. (Not an issue with the prius.)
