mph vs kph

[Roker]

My old Avensis had  method of changing kph into mph which is handy if we go across to the UK or travel up north. As most of us think in miles per gallon and not l/100km it would also be handy if Toyota gave us the choice like they did in the past

The 2023 models have the feature to choose either mph or kph, tyre pressures can also select bar or psi

True, but kph automatically gives you ltr/100km which, numerically,  goes the opposite way as you drive more economically. 

Useful one way: I have 300km to go, I need 15ltr

I assume my 2020 Corolla does not have this facility

Haven't checked but does the analogue display show both?

A subject that annoys me. In almost everything I'm metric. I'm 56 years old but I was only ever taught the metric system - possibly because the first school I attended was only built in 1970. But there are two areas where I'm imperial:

• Golf.
• Driving

For driving I think it's pointless trying to change. Distances and limits are in imperial so we're stuck.

Golf is more complex. There are some courses with distances in metric and I could always change my laser and GPS devices.

But I agree that the typical metric equivalent of 'distance travelled v fuel used' is confusing. Then again if you switch to use it you'll eventually work it out. Most of the metric v imperial debate comes down to familiarity. I used to measure my weight in stones but after switching the scales to kg I soon adapted. Now I don't understand any other kind of personal weight.

For short measurements metric is much simpler.  I mean, take a standard sheet or wood or dry roc, easy to remember it's 2.44x1.22 m.

I think I am right in saying it is metres an mm rather than centimetres for some reason.

In Canada. We were told a particular shallow lake was no more than a metre deep.  In winter it would freeze over with ice a foot thick.

Then there was that alliterative poem '

"Full nine metres thy father lies..."

I like that we're used to both and can use either without being confused, unlike a certain space organization who lost a satellite due to mixing up their units  

I tend to use metric for accurate measurements, but imperial for 'human' measurements.

Maybe it's just me but I find e.g. a pint or a foot much easier to get a feel for, but mm and cm beat inches easily when you want accuracy.

For a long time there wascan aspiration for a beach club.  Eventually it was decided to put it to bed, do it or scrub it.

It was decided to have an entrance, facilities, a bar and be extensible 

The architect came up with the plans and itcwaz put out to tender.  The tender was so reasonable that we thought to do much more.

Then the builder said he thought that it would be better,  and not too much extra, if the hall was 4 or 5 feet wide and not 3 as specified. 

Three metres OTOH .....

Swinging the lantern again as I do.

I can remember drawings for buildings having both imperial and metric dimensions on them at the same time.

The worst of all worlds.

Especially for the barely literate who had to read the headlines in the sun out loud in the tea hut to understand them.

And got confused by measuring tapes having numbers printed on them.

Modern tyre sizes are a mix of imperial and metric

The metric unit of length is the metre. Prefixes are then used to indicate multiples of. The SI system generally only uses prefixes that are factors of 1000. The centimetre is a rare exception because it's convenient I suppose but I think it's viewed as something of an ugly stepchild 🙂

I like that the metric system is self-referential which simplifies a lot of complex calculations. Unit conversion is also typically easier.

But of course the real advantage is that the metric system uses globally agreed units. There's no such thing as a UK litre or a US litre. A litre is the same volume the world over.

Oh and the imperial system doesn't really exist any more because its units are all defined as metric units anyway. 'inch' is just a short-hand label for 25.4mm 😉

 Centimetres in my opinion are an abomination,it adds a third component to dimensions which is unnecessary.

Metres and millimetres are perfectly adequate.

They even confuse people who can read a tape measure, never mind those who can't read with their tongue in silently.

Thankfully most construction drawings are in the format of metres and millimetres, and dispense with that nonsense.

Its also possable to have both displayed but the second reading on the smart phone.

You can select it to display MPH or Km for more accricy turn on GPS that part I have not tried.

Dont touch your phone in the car thats the UK law set it up before you go.
