can somebody please f!@#$% help me!!

[joseph84]

Does any one know how to convert kgs to psi? Ive just puchased a tyre inflater for my compressor and the damn thing only reads in kgs and pounds. Its bloody driving me up the walllll!!!!:mad:

Thanks for any help guys

Pretty much everything is in a variation of kPa (Kilo Pascals) or Bar where 1 Bar is equal to about 14.5 PSI

I myself run all of my motorcycles and cars in Bar and I know from experience that most cars, give or take require about 2.2 - 2.5 Bar pressure. 2 bar is 29 PSI and 2.5 Bar is 36 PSI.

I new this little book would come in handy one day.

it says....

kgs times 14 = psi.

So multiply kgs by 14 to get psi.
Make sense ?

Hope it helps Joesph.

[joseph84]

thanks guys :) so 32 psi is how many kgs? i never passed maths :D

[KevM]

PSI = pounds per square inch, no conversion is necessary or am I missing something.

Joseph, have a good look at your compressor gauge.

I think you will find that it reads in kPa which is KiloPascals, not Kg which is Kilo Grams which is a measure of weight not air pressure.

Anyway to answer your last question 32 PSI = 220.6324026 kPa.

Measure 2.2 and you will be alright.

Why do you need to convert kgs to psi :confused: when you say it already reads in pounds ? Who is confused here. :confused:

Guys Kgs are a measure of pressure!
1kg/cm2= 14.22psi/98.0665kpa
1kg/m2 =0.001422psi/0.009806kpa

[rick_rine]

I must admit this thread confuses me too . If it reads PSi and Kpa whats to convert , but anyway it reminds me of the Trysquare I bought last month , great quality but got peeved when I found both imperial and metric measurments on it . For goodness sake I'm 41 years old and was taught metric from kindergarten . So I dutifully wrote a letter of complaint to the importers who were nice enough to reply to my complaint ( after 2 letters and 1 e-mail ) They agreed with me but said they have 7 squares in stores all of which are duel measurement devices .

Try this it has all manner of conversions on it very useful, hope it helps.

P.S. could it be kpa - psi or visa-versa!...

So what is the conversion factor from Imperial degrees to Metric degrees???

So what is the conversion factor from Imperial degrees to Metric degrees???

Depends on the subject matter, I assume a Batchelor of Emergency Services Management (Imperial) from any US institution would be about one tenth of a (Metric) Batchelor of Fine Dining from any French one.

That's just an observation of course, and I suppose there would be a different weighting as to whether it was a two year or three year degree?

[ndru]

All I know is that I'm 0.4612 of a standard male lifespan old.

Soon I'll be 0.5128. Life was so much more fun when I was 0.2692. Now I'm just looking forward to retiring at 0.8461.

I really admire those people who have good health at 1.0256. Its amazing, to see some people live to 1.1538! :D

Peter,

I think it should be spelt waiting if you are talking about dining and French Cuisine. :D :D :D

[silentC]

What about a Bachelor of English Spelling?

Are you still jet lagged, BM?

Peter,

Ever come across a French waiter? Then you will learn all about waiting, and arrogance, and rudeness. :mad:

I understand that only the most patient and polite of Frenchmen get to be waiters.... ;)

Bugger! Yep...er no....prop-jet lagged this time (but the headcold is what did it....)

So people don't think this thread has been hijacked, the metric system started in France and the metric unit of pressure was named after him.

"Genius with a Heart of Faith; French Scientist Blaise Pascal Finds God and the Answer to Life's Deepest Mystery"

Did he find a way of convincing SWMBO to buy him more tools?

[zenwood]

Speaking of hijacking, Pascale made this point, which is interesting in relation to modern terrorism:

"Men never do evil so completely and cheerfully as when they do it from religious conviction."

[AlexS]

Think metric...it's a dozen times easier.

[Gingermick]

So what is the conversion factor from Imperial degrees to Metric degrees???


It's all a matter of degrees.



32 PSI = 220.6324026 kPa.


Are you sure its not 220.63240264 kpa :D
:)


Think metric...it's a dozen times easier.


Not the same as making it 1/12 as difficult.

[joseph84]

I double checked my tyre inflater today and yes im correct! On the measuring stick (if thats what you call it), one side has KG and the other POUNDS. Im just as confused as everyone else. I thought KGS was a measure of weight??

...and stop hijacking my thread!! :D :D

[vsquizz]

A pound in pressure talk is actually pounds per square inch

Kilograms in pressure talk is actually kilograms per square centimetre.

1 kgf/cm2 = 14.2233 PSI (=lbf/in²)

I recommend you download this gizmo, it takes up bugger all space and is as handy as....as.....a spellchecker that works:confused: .

So, Joesph.....when you line up by eye, on that measuring stick, what does 32 Psi equate to

if 1 kg = approx 14 psi.

1/14 = ?/32 ....... ? = 32/14 = about 2.3 kgs....

2.3 kgs ???? Does the measuring stick give you about that ?

Just curious how correct the conversion is.

[zenwood]

This is just a guess, so don't take it as gospel. I imagine the "Pounds" is an abbreviation for "pounds per square inch" and "KG" is an abbreviation for "kg per square metre". These are the standard imperial and metric units of pressure. You are right that literal pounds and kg are units of weight, not pressure, which should alway be expressed as "force per unit area".

Actually pounds and kg are not units of force, but are themselves shorthand for the force of a 1 pound (or 1 kg) mass acting under gravity. The force of 1 kg acting under gravity (9.8 m/s^2) is 9.8 Newtons, and the pressure of 1 Newton per square metre is called 1 Pascal: 1 kg/m^2 = 9.8 N/m^2 = 9.8 Pa.

Upshot: I suspect all of this is a non issue: the "pounds" scale on the pressure guage would be measuring imperial pressure, and the "KG" scale would be measuring metric pressure, kg (or Newtons) per square metre, or Pascals. Presumably you read off the required pressure from the side of the tyre (or wherever) and add air until the guage measures that amount (in the same units).

Clear?

1Kg exerts a force of 9.8N in the earth's gravitational field at the earth's surface.

You're right: post corrected.

[burn]

This thread is getting scarey

[joseph84]

my brain is really sore :D i didnt think it was going to get so complicated. But anyway thanks for the help guys, cant go past an Aussie when you need help! :) I think i will be throwing this tyre inflator in the bin!

[zenwood]

And, as Einstein taught us, this is all only valid in an inertial frame of reference.

Could do what I do . . . never check the tyres.:eek:

[joseph84]

Im with you Zenwood, Im just going to keep driving around till my tyres are totally flat!, or untill someone invents a tyre inflator that has a useable measuring stick! :D
