It's this Kev. https://www.thoughtco.com/definition...opascal-604551

But do we actually need to change from what is well known both sides of the channel?

The FSA formerly SIB & PIA licensed a twice convicted fraudster to handle our life´s savings. Guess what? He robbed us of £750,000. So they changed their name again to the FCA.

I got lost when we had bar to contend with, to my mind the smaller the unit of measure you use the more accurate you will be So psi wins.

We have had to adopt and get used to all sorts of new and old quantities. Imperial & Metric in material and foodstuffs. But we do adapt but sometimes it's a juggle.

Blood glucose is measured using two different units in the U.K. and very many other places….

mg/dl or mmol/l

Please don’t ask me to explain, that’s above my pay grade….. but one is 18x higher than the other…. (eg 10mmol/l = 180mg/dl) Quite a considerable difference……

A few years ago blood glucose meters in the U.K. used to be switchable between the two systems…..

Recipe for disaster as one elderly person suddenly found a blood glucose reading of 90……

Panic, panic ‘cos most of his readings were around 5.

So, thinking things were desperately wrong he gave himself boost after boost of rapid acting insulin and was found collapsed. Fortunately the hospital was able to treat with a glucose drip (probably more of a glucose flood than drip) and we’re able to work out how the confusion had happened. His case was far from unique.

No such switching is not permitted ANYWHERE, but it does show how the units involved MUST be understood before use.

So beware of kPa, b, and psi - don’t mix em up…. Tyres will go bang if inflated to 65 b and as for kPa, don’t even think about it as the rest of the MH could end up on the moon.

Any typo that I make means the errorists win.

Any comments above are only MY OPINION and should be read as that.

Having worked 8 years in Michelin actually putting all the bits of rubber, steel and fabrics together that make up a tyre and understanding the process Michelin put into tyre development, I’d ignore their advice at your own peril.

For those of us that put all the elements together, they employed 5 times as many in QC proving they met their high standards of uniformity criteria or otherwise run a gully knife through the sidewalls of the worst of the cured tyres making them only useful as dock boat fenders. The only element that could be reused before a tyre was cured was the steel ‘tringle’ bead band that provided the support for the wheel rim seating.

The people who passed off a pair of gloves as *two* items of PPE may not be entirely honest.

I run ours at 70psi all around and am happy with the ride and the wear patterns. We normally are running with a fairly full load as well...anything up to the full 5t.
