# Question for anyone using efunda.com

• posted

Hello All,

If there is anyone (and I know your out there) that uses efunda for finding material props for thier SW material DB's.

Could someone explain to my how to get N/in^2 from N/m^2? Or do you convert from something else and what? I have a great little program called Convert, but it doesn't have anything to do with Newtons that I could find. What I'm actually looking for is the Material properties for Acetel and/or Delrin.

TIA, Muggs

Hi Muggs, Best point to go for materials info is

To convert from N/in^2 to N/^m2 you'd divide by 1550 (roughly) just on a units conversion. (1550 square inches in 1 square m) HTH, JOe

As always, Google is king. Simply enter something like this in the Google seach box:

14.7lb/in^2 = ? N/m^2

and you get something like this in return:

14.7 (lb / (in^2)) = 101 352.932 N / (m^2)

So in your case it would be:

x.xxN/m^2 = ? N/in^2

Complete instructions here:

Thank you Tick,

I wasn't going to go there because I thought maybe it's a standard measurement that I was unaware of, but that's exactly what I was thinking. But I'm thinking SW is making strides because in SW2004 it was in N/m^2.

Hi again,

...just forgot to mention that both of them (Calc98 & Versaverter) can be customized so that new units can be added... (and that is what I like so much about them)
