How to set Algor to metric system

Just a note for metric units for "small dimensions":
A more common consistent metric unit set (apart from basic SI) is:
Mass in tonnes (1,000 kg)
Length in millimetres
Time in seconds
Force in Newtons
Stress in MPa
Energy / Work in milliJoules
Personally, I try to work in basic SI for all models if at all possible, because then I can be 100% sure that the required units for any uncommon model parameters with which I may not be totally familiar (e.g. specific heat, thermal conductivity coefficient, etc) will all be in their basic SI values (J/kg/K & J/s/m/K respectively).
If I am working with imported CAD geometry (where the dimensions are often in mm), then I will use the above unit system, but extreme caution is required when entering any "unusual" or "derived" parameters, to make sure you get the factors right. For example, density is in units of tonnes per cubic millimetre (which is a VERY small number, unless you reside on the surface of a neutron star
).
