Kn/m2 to Kpa
Hi guys,
Just like to know the proper procedure in converting the following: 1. kg/m3 to kg/m2 (unit weight of concrete devide by nominal thickness of concrete i.e. 2,400 kg/m3 / 0.09318m = 25,756.6 kg/m2, is this correct?) 2. kn/m2 to lbs/in2 3. lbs/in2 to Kpa Thanks in advance to those that will be helpin' me out on this.

kg/m³ * m = kg/m² Quote:

A kilopascal (kPa) is the same as a kilonewton/square meter (kn/m²). so number 2 and 3 are very much related.

Re: Kn/m2 to Kpa
just like to addup
Is kg/m3 * m3 = kg/m3? i forgot to list it in my previous querry. i.e. unit weight of concrete multiplied by the calculated volume  will the product be still kg/m3? Again, Thanks in advance for the replies.

Re: Kn/m2 to Kpa
No, it would be:
kg/m³ * m³ = kg Its just regular algebra, the m³ cancels each other out. What you have is the volume, multiplied by the density, gives you the weight.
