HP35s any good for EE?

You're right also but I guess NOT every engineer knows that 1_Pa = 1_J/m^3.

When I learned statics and mechanics (from 1999 to 2004), we used always MPa for stress calculations. Of course the tables gives properties in cm^3 and mm^4. All force in practice always kN. Old engineers "feels the range" when they are make a division of kN*m/cm^3. But I need a "conversion" because in my head everything is MPa. My 48SX is perfect for this.

For fluid flow calculations (m^3/h, l/min, bar, mmWG, Pa, etc...) I can feel the right values.

It was an example for unit conversion only, this is not a real life calculation. But you're right this beam section property typically given in cm^3.
