Q. Density of liquid in CGS system is $0.625\ \ g\ {cm}^{- 3}.$ What is its magnitude in SI system?
A) 0.625
B) 0.0625
C) 0.00625
D) 625
Explanation
We know that $\ \ \ \ \ \ \ \ \ \ \ density = \frac{mass}{volume}$ In CGS units $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ d = 0.625\ {gcm}^{- 3}$ In SI units $\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ d = \frac{0.625 \times 10^{- 3}\ kg}{10^{- 6}\ m^{3}} = 625\ {kgm}^{- 3}$
