Can someone explain to me the mesurements, I am so confuse

How do you get MPa? Is it N divided by mm, or KN divide by m

Please give me a detail conversion, without using those divide symbol thing, coz i don't get then.
Also how many N = KN??

1000 Newtons (N) in a Kilonewton (kN), just as there are 1000 grams in a kilogram...

As to the MPa, Pascals are a measure of stress, or force per square metre of area. Normal pascals (Pa) are in Newtons per metre squared (N/m^2), so kilonewtons would then be in kilonewtons per metre squared (kN/m^2), and megapascals are in meganewtons per metre squared (MN/m^2). So in your terms, its MN divided by m squared.

Did that help?

ok, this is what I have learned,
Newton divided by mm square = Pa = kN divided by m square
right?

no tieki stop confusing ppl...i will clarify it for you survivor

1 Pascal=1 Newton spread over an area of 1 metre squared
1 Megapascal=1 million Newtons/1 square metre
=1 Newton/1 square millimetre
=1000 kN/1 square metre

again, I recommend that you don't try and learn all of these forms, but remember the first one only and derive the following three according to the form required for the question...
also, be familiar with your prefixes:

deci=x10^-1
centi=x10^-2
milli=x10^-3

kilo=x10^3
mega=x10^6
giga=x10^9

those are all the numerical prefixes you should know for the engineering studies course
