Question

How to convert in to SI to cgs

Answer 1

Answer:

1m = 100cm

1kg= 1000g

so, if the density is 100kg/m^3

in SI units

100×1000/(1×100)^3

= 0.1g/cm^3 in CGS units

the unit for time is same in both the systems - seconds (s)

Answer 2

Answer:

In SI units

G=6.67408*10^-11 N m^2 Kg^-2

we know, Force = Mass * Acceleration

So N= Kg.m s^2

G=6=67408*10^-11 Kg.m.s^-2.m^2.Kg^-2

G=6.67408*10^-11 m^3.Kg^-1.s^2

In CGS,

G ~6.67408*10^-11 cm^3.g^-1.s^2

So you can use reverse way to convert CGS to SI
