How do they check your body density?
Measurements. Underwater Weighing — body density can be measured using the hydrostatic weight technique. Whole-body Air-Displacement Plethysmography (BodPod) — measures body volume and weight to determine density.
So it's pretty accurate to say that a 95 kg person has a volume of 95 liters. It's probably accurate within 5% or so. Actually the density of the human body is very close to that of water--that's why most of us (depending on fat content) sink when we exhale and float when we inhale.

The average volume of human body as measured by water displacement; data based on sample of 521 people, age range 17-51 years is about 66.4 L or 0.0664 cubic meters.
- The SI unit for length is meters(m), for mass is kilograms(kg), for volume is cubic meter(m^3), for density kilogram per cubic meter(kg/m^3), for time is seconds(s), and for temperature is kelvins(K).
- Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. By international agreement, absolute zero is defined as precisely; 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale; and –273.15 degrees Celsius on the Celsius scale.
- Stellar black hole: mass = 2× 1031 kg, volume = 3.4× 1012 m3 . The density would then be mass/volume, or 6× 1018 kg/m3 . Galactic sized: Mass is 2× 1039 kg, volume= 1037 m3 , density= 200 kg/m3 . It seems that the larger they are, the less dense they would be, but only if you consider the event horizon as the limit.
- A Dictionary of Food and Nutrition. body density Body fat has a density of 0.90, while the density of fat free body mass is 1.10. Determination of density by weighing in air and in water, or by measuring body volume and weight, permits calculation of the proportions of fat and lean body tissue.
- The density of blood plasma is approximately 1025 kg/m3 and the density of blood cells circulating in the blood is approximately 1125 kg/m3. Blood plasma and its contents is known as whole blood. The average density of whole blood for a human is about 1060 kg/M3.
