Frequently Asked Questions

Density equals mass divided by volume (D = m / V). The SI unit is kilograms per cubic meter (kg/m3), but grams per cubic centimeter (g/cm3) is common for solids and liquids.

Pure water has a density of approximately 1.0 g/cm3 (1000 kg/m3) at 4 degrees Celsius, which is its maximum density. The density decreases slightly at higher temperatures.

Measure the mass using a scale, then determine the volume by submerging the object in water and measuring the volume of water displaced (Archimedes principle). Divide mass by displaced volume to get density.
