[QE-users] Atomic velocities units

[Lorenzo Paulatto]

It depends on which units you have specified for atomic positions. Regarding time,
1 a.u.=4.8378 * 10^-17 s

kind regards

I'd like to use the atomic positions and also velocities from another run in Angstroms and Å/picoseconds to the QE input, but I am not sure about the units I need to use. In the documentation, there says it should be atomic units, and when I read the co.c documentation it was the same, but in the description they mentioned we needed to use the units as they're in the atomic positions card and time in a.u. does anyone have an idea of what convertion should I use?
