Formula
How this is calculated
Density measures how much mass is packed into a given volume, so every unit here is a mass unit divided by a volume unit (for example kilograms per cubic meter, or pounds per cubic foot). To convert between any two of them, the tool first normalizes your input to a single base unit, the SI standard of kilograms per cubic meter (kg/m3). Each unit carries a fixed "to-base" factor: 1 kg/m3 is the base (factor 1), 1 g/cm3 equals 1000 kg/m3, and 1 lb/ft3 equals about 16.0185 kg/m3.
The conversion is a single proportional scaling: it multiplies your value by the source unit factor to reach kg/m3, then divides by the target unit factor. Equivalently, value_to = value_from x (factor_from / factor_to). Because g/cm3, g/ml and kg/L all map to the same 1000 factor, they are numerically identical and convert one-to-one.
The factors are exact for metric units; the imperial ones (lb/ft3, lb/in3) come from the international pound and inch, so results are rounded to a few significant figures. The math is purely linear with no offset, so it assumes uniform density and makes no correction for temperature, pressure or material composition.
About this calculator
Density is mass per unit volume. The SI unit is the kilogram per cubic meter (kg/m3), but laboratories commonly use grams per cubic centimeter (g/cm3), which is numerically identical to grams per milliliter and kilograms per liter. For reference, pure water has a density of 1 g/cm3, or 1000 kg/m3.
This converter uses kg/m3 as its base unit. Note that 1 g/cm3 equals 1000 kg/m3, while one pound per cubic foot equals about 16.0185 kg/m3. It is useful for material science, fluid mechanics and chemistry.
Frequently asked questions
Pure water has a density of about 1 g/cm3, which equals 1000 kg/m3.
Multiply by 1000. For example, 2.7 g/cm3 (aluminum) equals 2700 kg/m3.
Yes — one milliliter equals one cubic centimeter, so g/ml and g/cm3 are numerically identical.
