If I want to convert the surface tension converted into lattice units which fator shold I use? Since The units of surface tension is N/M.
Should I use 0.133333/0.0144?


Voxel length(m):                  physDeltaX=     0.133333
Time step(s):                     physDeltaT=     0.148148
Velocity factor(m/s):             physVelocity=   0.9
Density factor(kg/m^3):           physDensity=    1
Mass factor(kg):                  physMass=       0.00237037
Viscosity factor(m^2/s):          physViscosity=  0.12
Force factor(N):                  physForce=      0.0144
Pressure factor(N/m^2):           physPressure=   0.81
