# 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**.

### What is the average volume of the human body?

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.#### What is the volume of an average person?

Hello Anezka,

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.#### What is the SI base unit of volume?

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).#### What is the significance of the temperature of absolute zero?

**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.

### What is the average density of the human body?

985 kg/m³

#### What is the density of a black hole?

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.#### What is density in the body?

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.#### What is the density of blood?

The**density of blood**plasma is approximately 1025 kg/m^{3}and the**density of blood**cells circulating in the**blood**is approximately 1125 kg/m^{3}.**Blood**plasma and its contents is known as whole**blood**. The average**density**of whole**blood**for a human is about 1060 kg/M^{3}.
