conversion from SI unit to gm/mm/ms unit system:
SI unit mg/mm/ms unit
MASS 1kg 10e6mg
LENGTH 1m 10e3mm
TIME 1s 10e3ms
FORCE 1N 10e-3N
STRESS 1Pa 10e3Pa
ENERGY 1Nm 10e-6Nm
DENSITY 1Kg/m3 10e3Kg/m3
YOUNG'S Modulus 210GPa 210e6Pa
Velocity 56.33KMPH 56.33KMPH
GRAVITY 9.8m/s2 9800m/s2
Mass: 1kg=1000g=10e6mg
Length:1m=10e3mm
Time:1s=10e3ms
Force: 1N=1kg*1m/(1s*1s)=10e6mg*10e3mm/(10e3ms*10e3ms)=10e3(mg*mm/ms/ms)
Stress: 1Pa=1N/(1m*1m)=1Kg/(1S*1S*1m)=10e6mg/(10e3ms*10e3ms*10e3mm)=10e-3(mg/ms/ms/mm)
Energy: 1NM=1kg*1m*1m/(1s*1s)=10e6mg*10e3mm*10e3mm/(10e3ms*10e3ms)=10e6(mg*mm*mm/ms/ms)
Density: 1kg/m3=10e6mg/(10e3mm*10e3mm*10e3mm)=10e-3(mg/mm3)
YOUNG'S Modulus: 1Gpa=1e9pa
Velocity:km/h=10e3m/3600s=10e6mm/(3600*10e3ms)
Gravity:m/s2=10e3mm/10e3ms/10e3ms=10e-3mm/ms/ms
