You speak of #"density"#, #"mass per unit volume........"#

Explanation:

We define #"density"#, #rho#, by the relationship:

#rho="Mass"/"Volume"#.

Typically (for chemists) #rho# has units #g*mL^-1# or #g*cm^-3#.

#=# #g*cm^-3# #=# #g*(10^-2m)^-3#

#=# #g*10^6*m^-3#

#=# #cancelgxx10^-3*kg*cancel(g^-1)xx10^6*m^-3=10^3*kg*m^-3#
