Conversion of SI units to gm-mm-ms.
Mass 1kg in SI units, 1000gm in gm-mm-ms unit system
Lenght 1m in SI units, 1000mm in gm-mm-ms unit system
Time 1s in SI units, 1000ms in gm-mm-ms unit system
Force is 1N i.e., 1kg-m/(s^2), => 1000*1000/(1000^2) gm-mm/(ms^2) =1 gm-mm/(ms^2).
Stress is 1Pa i.e., 1kg-m/((m^2)-(s^2)), => 1000*1000/(1000^2)*(1000^2) gm-mm/((mm^2)-(ms^2)) =10^-6 gm-mm/((mm^2)-(ms^2)).
Energy is 1Nm i.e., 1kg-(m^2)/(s^2), => 1000*(1000^2)/(1000^2) gm-(mm^2)/(ms^2) =1000 gm-(mm^2)/(ms^2).
Density is 1kg/(m^3), => 1000/(1000^3) gm/(mm^3)= 10^-6 gm/(mm^3).
Youngs modulus is 210GPa i.e., 210*10^9 kg-m/((m^2)-(s^2)), => 210*10^9*1000*1000/(1000^2)*(1000^2) gm-mm/((mm^2)-(ms^2)) =2.1*10^5 gm-mm/((mm^2)-(ms^2)).
Velocity is 56.33 KMPH=> 56.33 *1000*1000/(3600*1000) mm/ms=>15.6472mm/ms.
Gravity is 9.8 m/(s^2),=> 9.8*1000/(1000^2) mm/(ms^2)= 9.8*10^-3 mm/(ms^2).
