KN/m2 ???
How do i work out KN/m2, can anyone help???
Thanks. Dave.

Re: KN/m2 ???
Can you provide more information as to what you are trying to do?
You need to convert that to something else, or convert something else to that?

Re: KN/m2 ???
what does Kn/m2 mean in context to the weight of a dead load....i.e. a house?

#4




Re: KN/m2 ???
It's a unit of pressure, force per area. For a weight such as a house it would be how much weight over a specific area.
kN = kilonewton, a unit of force. m2 = m² = square meter, a unit of area kN/m² = kilonewton/square meter You can convert kilonewtons to poundsforce or kilogramsforce, if that will make it easier to understand.

Re: KN/m2 ???
so if is stated that the floor can support 100KN/m2, it means it can handle a average weight of 100kg per m2?

Re: KN/m2 ???
Unfortunately, it's not quite that simple.
One newton is approximately equal to onetenth of a kilogram (0.1 kg). Since the floor you're describing can support 100 kN/m^{2}, that's 100,000 N/m^{2}, or 10,000 kg/m^{2}. So the floor would be 100 times stronger than you thought. Hope that makes you feel safer!

This is derived by the weight in kilograms, times the force of gravity. I learned that here, from a poster called.... um.... and then we've been using it all the time at work, since.

Re: KN/m2 ???
Surely you're joking, Mrs X! *
But I don't know your sense of humor well enough to be sure. On the chance that you are serious, please read the last line of Post #9 in the following thread, to which I believe you are referring http://forum.onlineconversion.com/showthread.php?t=5091 "To convert from kilogramforce (kgf) to newton (N) Multiply by 9.80665"In equation form, that statement says: 1 kgf = 9.80665 NOr, inverting, 1 N = 1/9.80665 kgf = 0.101972 kgfNow, on the chance that you really were serious, I will let you claim that you were joking, as even Einstein was known to have made mistakes, and your good works in this forum have surely earned you many free passes from all.... But please, please assure me that you haven't really been using your stated formula at work!? Oh, and one more item of important businessTo both you and janiceruth, my sincere apologies for bulldozing you in that earlier thread, but I was terribly concerned about that poor school student picking up an incorrect answer and remembering it for the rest of his/her life! And then having other people also read it without correction. We wouldn't want the same thing to happen in the current thread either, now would we? So, I repeat my assertion: 1 N = 0.1 kg (approximately)and I claim that this is equivalent to what I posted in that earlier thread. * In case you didn't catch the pun in my greeting, it comes from the title of a delightful book about... a physicist! Imagine that! http://www.amazon.com/SurelyFeynman.../dp/0393316041

Re: KN/m2 ???
Oh duh! We discussed it, and still I got it wrong! I should stick to chemistry, and not worry about physics.
1kg gives 9.8 Newtons. Most people just multiply weight (in kg) by 10 to get newtons.
