Milligrams per liter and kilograms per cubic meter are both measurements of density. Density describes the mass of a material or object in relation to its size; you could have an equal volume of lead and feathers in two boxes, but the box of lead would have a greater mass as it is a denser material.

There are a number of simple web-based tools online to help you convert densities as well as other measurements. One such tool can be found at www.unitconversion.org/density/kilograms-per-cubic-meter-to- where you simply enter the measurement you have and the unit type you want to convert it to, and it will do the rest for you. The website also has a more complete density conversion calculator, with over 2,100 different units of measurement, including:

www.engineeringtoolbox.com/density-converter-d_1038.html is a web page which contains a table detailing the formula for calculating density conversions. The table allows you to find the two units you are converting between, and tells you how much to multiply each one by to find its converted value.
