1 kg/L equals exactly
1 g/mL
As with the inverse conversion, going from kg/L to g/mL the numerical value remains identical: this is one of the few density conversions where no calculation is needed, since the two units represent exactly the same scale (mass in thousands of grams over volume in thousands of milliliters).
To convert a measurement from kg/L to g/mL, the numerical value does not change:
Likewise, to convert from g/mL to kg/L:
This equivalence is particularly useful for those working with fuels, oils, or other industrial liquids, where density specifications may be reported in either unit depending on the source (safety data sheet, delivery note, technical manual), and knowing they are interchangeable avoids confusion.
