Physics Question on physical world

Density of liquid in CGS system is 0.625 g/cm30.625\,g/cm^{3} What is its magnitude in SI system?

A

0.625

B

0.0625

C

0.00625

D

625

Answer

625

Explanation

Solution

We know that, density = massvolume\frac{ mass }{ volume }
In CGS units d=0.625 g cm−3d = 0.625 \, g \, cm^{ - 3}
In SI units d=0.625×10−3kg10−6 m3d = \frac{ 0.625 \times 10^{ - 3} kg }{ 10^{ - 6} \, m^3 }
=625 kg m−3= 625 \, kg \, m^{ - 3}
