1*dm^3-=1*L-=1000*cm^3-=10^-3*m^3.

Explanation:

d is the abbreviation for "deci"=10^-1.

Thus 1*dm^3 = (1xx10^-1*m)^3 = 1xx10^(-3)*m^3

c is the abbreviation for "centi"=10^-2.

And 1*cm^3 = (1xx10^-2*m)^3 = 1xx10^(-6)*m^3

And thus there are 1000*cm^3*dm^-3, or 1000*cm^3*L^-1

And there are also 1000*L*m^-3. A "cubic metre" is a very large volume.

And thus 1*mol*dm^-3 = 1*mol*L^-1, which is the familiar unit of concentration.
