This is a new one on me

I'd forgotten the tyre pressures for the Volvo so had to resort to the manual. And there they are, totally unintelligible. 230 front, 210 rear. Whaaaat???:confused::confused:

Most peeps in the UK work in psi. Garage pressure gauges might work in Bar. But this is KPa - kilopascals. I'd never heard of them. To get to bar, you divide by a hundred. So, 2.3, 2.1.

Where did these come from...:confused:

Welllll.....they obviously came from the book that only old people can read, when wearing yellow plastic over their specs lenses. :rolleyes:
Tiz secret text, ya see, all will become clear when you find the yellow plastic, inserted in the back of the manual;)

I thought that was pretty normal, I do a lot of miles so always check tyre pressure and most cars I've had have had the pressures noted in PSI, BAR, KPa

[Stenno]

KPa I believe is metric and the agreed unit under the SI. Psi is an old imperial measure. Bar is an old British measure.

At work we have all three on various systems and equipment. I guess it's a bit like the fact you can still buy a pound of strawberries at a fruit and veg market. It would be ridiculous to retrofit every single piece of equipment using the old measures.

Ed, you aught to try servicing anaesthetic machines, especially older ones.

The gas going in is at 4 bar = 58psi give or take a midge's whatsit. The gas going to the patient, or test lung for engineers, used to be measured in litres but for pressure it was in millibar.... or centimetres of water, and now kpa. But its still 4 bar going in.

And giving one of our new/young engineers a job on an old machine to service... if it were a patient on the end of it they'd have lungs like a couple of Spacehoppers by the time the engineer gases up the test lung.

I work in KPa in very small amounts

[Paul the 6th]

so it's the metric version of pis?

[embee]

It wasn't a preferred unit, but some engine management system suppliers used to work in "torr" (= mm of mercury, mmHg), so 100kPa = 750torr or thereabouts.

[Paul the 6th]

or psi? what did proper spelling ever do four a knee won

[MisterTommyH]

so it's the metric version of pis?

Kind of.

Imperial = Pounds per square inch or psi

Metric = Kilonewtons per metre square or kPa

If blowing up your tyres, get a digital tyre gauge, they convert for you so no need to even think about it.

As long as manuals give the Kpa as well as psi / bar then it's not a problem.

[Ed]

Yes peeps - but having a brain that still works in pounds shillings and pence, I had never heard of KPa. And the Ovlov's a C30:D
