It always has and always will..
My daughter and grandchildren use metric.. I always have to convert measurements when ordering/buying goods.. When weighing the turkey at Christmas I ask a friend.. :smiley:
Are they knocking metric on the head.. ?
I blooming well hope so, centipedes and millipedes means nothing to me have to convert it into good old Imperial.
One of the benefits of living here of course, feet and inches, lbs & ozs gallons & pints again - wonderful. I believe the choice to use whatever system is easier should have been the rule in the UK. Of course the wretched EU prevented that freedom! Insisting by law that only decimal fractions could be used and Sunderland trader Steve Thoburn was fined £2k in 2001 for so doing. A true sign of the jackboot and the lies cast by Edward Heath et al back in '72/3.

Just making it legal to flog stuff in imperial weights and measures I think. Dunno if it includes buying stuff by the yard but pints are back in favour along with crowns on the glasses. Both imperial and metric will be allowed though.
when the timber trade went metric way back, went to the local timber yard wanting some 2x4 so asked for two metres of 50x100 mm
'Sorry' - only sell in multiples of 300mm - which is?
Mike
Lengths of timber are often 1.8m and 2.4m too :grin:
I think we have to wait until all the trees have gone fully metric.
I remember winning a bet with an American,saying that British drivers always get higher mpg. He got quite irate especially when I blamed Queen Anne. Then , I told him that American gallons were smaller, and laughed and paid up. One Coors Light later, we were friends again.
It's odd that we were using cc for engine sizes long before we were pushed into going metric in most areas. We even had a British motor industry back then too. Before my time but I think they were classed in horse power earlier too and BHP still gets a mention but using kW seems to have crept in as well.

Yes the Woke will soon be boasting how many volts to the mile they achieve! :nooo:
(ps, sorry kilometer)
A long time ago 'horsepower' was a calculation for taxation purposes and was based on the engines capacity, not its actual power output, for which the only measure that I can understand is BHP.
Mike
My son is far from woke but he got an electric car because it would save him money. It actually shows you in an info panel how many miles it is averaging her kWh :grin:
He was well pleased the other day when the warm weather improved the economy and sent a pic to my WhatsApp.

so with a -say- 70 kwH battery that's a range of 280+ miles - not bad. What dies he get in winter with lights, heater etc., on?

I see. As I said before my time.
There is a direct conversion between HP and watts from memory it's ~ 750w is 1HP. Outboard motors get rated in HP still as are some lawnmower engines or at least they used to be. Not sure about the fancy ones you ride.

Actually looking at the ones in the link I dug up his is the 77kWh one. He only got it in November. I think it still gets better than 3. We go to his boat fishing most Saturdays during the season and have only spent any time talking about it when I've been in it on fishing days. He calls it his dog eater as they are made in Korea but seems to really like it.
The other difference is that town driving doesn't take so much of a toll on economy as it does with internal combustion engine cars. I think it's the regenerative braking that helps and yours will have that too.

Looked it - never could remember 768W - 1bhp. My mower is, from memory - raining too heavy to go and look, is I think 15 bhp

Yes, it does. One irritation - the display has two meters- one shows the overall mileage - just coming up to 5,500, the other I reset every week. Both show total mileage and how much of it was achieved on electric power - always between a third and a half of the total - except the overall meter somehow managed to reset itself a week or two back and now claims only about 350 of the 5,500 miles were on electric, whereas before it managed to reset it showed over 2,000 out of 5,000
Mike
The firmware for these cars will all be fairly new and new usually means buggy.
Here's another nutty electric car fact. As you know an automatic in D with the engine running will creep unless you hold it with footbrake or handbrake. There is absolutely no reason why this should happen with an electric but my sons at least and probably all still does so. I'm guessing the firmware is set up to make them as close a driving experience to internal combustion as they can achieve.
I don't know how hybrids actually work. If all the drive comes from the electric motor and the ic engine just charges the battery then the same applies to them. I imagine they may well work that way as it has to be simpler but that doesn't stack up with the two mileages unless the ic just stops and only runs when the battery drops below some preset level.
I read (most of) a long article in Wiki and am now more confused than ever. All I know about mine is that you can actually hear and sense the IC coming in at low speeds, but above about 15 mph you can't hear it except under hard acceleration as wind and tyre noise tend to blot it out from my admittedly pretty poor hearing
Mike
I must read up on it (technology fascinates me). As I see it there are two options - you either have a standard electric car set up (which I don't know in detail) and the IC runs an alternator to charge the drive battery or you have and IC and an electric motor and some mechanism for mechanically merging the outputs. The first sounds simplest to me.
pretty sure mine is the second - you can feel - at parking speeds - the engine cutting in and the creep speed increase fractionally

says
Transmission:
The transmission transfers mechanical power from the engine and/or electric traction motor to drive the wheels.
So it does seem both IC and electric get combined. I'm a little surprised as I would had thought that was more complex. My O level woodwork has let me down again. :worried:
The Wiki article I mentioned got my head hurting in no time!
Mike
I might read something more complicated later. I just wanted the Janet and John version (aka executive summary) to check which basic design type was actually used.
i think you will find we are stuck with the metric as this has been taught at schools for about fifty years
