input-scaling-factors

The base system for units is SI. However, all input quantities are assumed to be given in scaled form.
For physical constants, see$physical-constants.

Syntax

It is assumed, that input numbers are scaled to these "units".

Note:

[h_bar^2/(2*m0)] = kp_k^2_zb = kp_k^2B_wz

Scaling quantities are stored inMODULE mod_input_scaling.
