problems regarding conversion to reduced unit

Dear Lammps users,

I want to simulate in reduced lj unit using the mass m = 18 a.m.u., distance σ = 2.3925 Å
and energy ε = 3116.0686 K of the monatomic water model (mW). How will I convert temperature, pressure and time in reduced lj unit

using those available data.

Kindly help me .

regards,
