How to get to GPa?

Hi,

I have calculated the young modulus of a system by calculating the second derivate of the energy against the axial strain and then I devided the result on the volum.

The unit of the energy is eV and the volume is in angstrom^3. I want to calculate the young modulus in GPa, should I consider a coefficient? how could I get to GPa out of [eV/(angS^3)] ?

Regards,

convert to SI

Hi saray1360! :smile:

Pa is an SI unit, so you need to convert everything else to SI units first.

angstrom is easy :biggrin: … but eV is totally non-SI, so you'll need to find the factor to convert it to joules. :wink:
