Why in S.I system density is Kg/m3? And why not in S.I system surface tension is Kg/m but N/m? 
Yashodha said: (Aug 11, 2015)  
Density = Mass/volume. ρ = m/v. S.I unit is kg/m3. 
Maruthi said: (Jun 29, 2016)  
Density = mass/volume. Mass in kg and volume in m^3 so, density obtained in kg/m^3.

In S. I system force and pressure written as N. So, unit for surface tension is N/m and unit for density is kg/m3.

I think it should be N/m3.

Mass density  kg/m3. Weight density  N/m3. 
Maddy said: (Feb 8, 2019)  
Density = mass/volume (kg/m^3). Surface Tension = force/unit length(N/m). Force (=N) = m (=kg) * a (=m/s^2). Therefore, ρ = m/v. S.I unit is kg/m^3.

Density, Mass density = kg/m3. Weight density = N/m3. So, Ans is also A and B?
