# Thread: Volume of average human body?

1. ## Volume of average human body?

This, I know, is not related to workout programs, but I can't find this info anywhere. I dont feel like getting in some tank filled with water to see the overflow and measure it.

Anyone know an average person's volume / capacity? in gallons would be most helpful.

Thanks guys

2. Anybody? any info at all?

3. 20.9454545 US gallons

4. this question can never be answred. what is an 'average' person?

Since you seem to have failed math class...

....the unweighted average is the arithmetic mean which can be easily determined for any closed set as follows:

Since the volume of every person who is currently alive is clearly a closed set we can easily determine the "average volume" (or "average" of any other measurable attribute of humanity such as average IQ or average bench press).

To the original poster: is there something wrong with the answers that google provides when you search for "volume of human body"?

Hi speagle.

Since the average density of flesh is approximately the same as that of water, we don't need calculus(infinitesmal or otherwise) to do this.

Simply take the mass in kilos and say that the volume is the same in litres.

eg. if I'm 95kg, I'm 95litres. The average first world male is somewhat smaller than this. Look that up. Worldwide, the average male is a good bit smaller. Females on average are about 15-20% smaller(in most societies) than the males.

Since your volume changes about a liter when you inhale and exhale, we have typically little more than 1% error due to this factor.

Since the density of fat is less, fat people have somewhat more volume than their weight suggests.

With extremely lean individuals, the reverse is the case.

Even tho' bones are more than twice as dense, their volume as a percent of body volume is small, so the error due to bone size and density(which is affected by weight training) is very small.

If you are trying to stuff a body into a trunk........ya didn't get any help from me.

Hope you find this.........useful.......I think.

7. are you serious??
this is a joke.
VOLUME AND MASS HAVE NOTHING TO DO WITH EACH OTHER.

take an excersise ball for example. This ball is hollow, this ball has a volume of 50L per se. it weighs 1Kg

lets take a cannonball
it has a volume of 50L per se.
it weighs 100Kg for example.

flesh does not weigh similar to water. All your calculations are wrong

go back to bio
go back to math
go back to school

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. Muscle weighs about 1.06 g/ml, and fat is .9 g/ml. And we are made mostly of water. 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.

I think you need to do the math.

People are very similar in density to water, otherwise they couldn't swim just breaking the surface or underwater.

I was in school long before you were born, or so I thought from your answer until I saw your age. I'm still learning. About time you started noticing the obvious connection between the density of people and water allowing a mass measurement to give a pretty accurate handle on the volume, without holding them underwater in a giant displacement can to drown(actually a good idea for some people).

Strong first post lol

And volume = mass over density

Looks to me like they have something to do with each other.
