Question

what is the value of the ratio of si unit or cgs unit of density

Answer 1

SI unit of density = $\frac{kg}{m^3}$
CGS unit of density = $\frac{g}{cm^3}$

1kg = 1000g
1m³ = 100cm × 100cm × 100cm = 10⁶ cm³

$Ratio= \frac{kg}{m^3}/ \frac{g}{cm^3} = \frac{10^3\ g}{10^6\ cm^3} / \frac{g}{cm^3}=\frac{10^3}{10^6} \times \frac{g}{cm^3} / \frac{g}{cm^3}=\frac{10^3}{10^6}= \frac{1}{1000}$

So the ratio of SI unit and CGS unit of density is $\boxed{1:1000}$
