Electric car energy measurements.

[David Paste]

Why are they reported in kWh and not MegaJoules? It pisses me off to an unreasonable degree.

[Richard]

The fact that someone who should be capable of coping with the difference between kWh and MegaJoules is whining about it is even more absurd.

[Andy Burns]

Off the top of your head, what's your fossil-fuelled car in MJ?

[Tim+]

Exactly. Remind me, how many MPL does your car do? When did anyone last buy a gallon?

Tim

[Clive Arthur]

Mine gets about 0.06 mm^2.

[Andy Burns]

Yes, I've always been tickled by that area being equivalent to a tiny scoop you'd need, if petrol was in a trough down the centre of the road, like water was for steam engines!

[Andy Bennet]

I get about 3 cubic lace holes per fortnight.

[Colin Bignell]

Presumably because, if you are charging one from the mains, you are paying for the electricity used per KWh consumed.

It pisses me off to an unreasonable degree.

Completely unreasonable IMO.

[Max Demian]

Yes and why don't electronic kitchen scales measure in centi-newtons rather than grammes? The gramme is a unit of mass; electronic scales measure weight, not mass.

And don't take one to the Moon. All your recipes will turn out wrong. You need a beam balance.

[Max Demian]

The metric measure of fuel efficiency is litres per 100 km, so it works the opposite way round.

[Tim+]

That is simply perverse and belongs in foreign parts, not here. ;-). As we still have odometers calibrates in miles it would cause even more confusion.

Tim

[Clive Arthur]

That's fuel inefficiency, Shirley?

[Mike Clarke]

It'll be fine. You just get a much bigger cake.

[JNugent]

Hmmm...

Metric fuel consumption is measured in the number of litres required to do 100km, not kilometres (or miles) per litre.

[Chris Hogg]

How about 'hours to recharge'?

[Max Demian]

Not if you count the eggs. And some ingredients are measured by volume.

[williamwright]

I wish it was possible to increase the mass of an object without increasing it's weight. So many things could be lighter.

Bill

[Tim Streater]

Removing the incorrectly inserted apostrophe in your sentence above will make it lighter.

HINT: "it's" is short for "it is" or perhaps "it has". This is always true.

[Tim+]

Because that?s not a constant. Depends on the supply.

9L is 2gallons. So when buying fuel I often buy multiples of 9L to make the L to gallons conversion simple. Divide L by 9 then by 2 to gallons. Then mpg is easier to calculate. Then I press a button on the info screen and see what the car thinks and I can compare the two.
