As for a normal human, they are not 100vl, they are closer to 10vl. It is the seat/space for a human to ride or operate within a vehicle that takes up at least 100vl.

For the vl I suggested I just took your size of about 5m tall and guessed it at 1m through and 2m wide as an averaged. It's close enough for the design steps and nice round numbers are easier. Then once it's all run through I usually just fudge to fit the description.

Aren't "vl"s *liters*? If so, 5m x 2m x 1m would be 10,000vl.

Nope, the book says it's 10L to 1vl.

OK, Dan. I haven't had time to explore T20.

No problem Fritz, didn't mean it to sound snarky if you got that impression
Just short on time.

why not use liters or m^3 from the start?

well anyway... something just dawned on me (it is 0530 afterall ) 1cubicfoot is roughly the volume of one human ... so i weigh 200pounds and displace 1cf. Gurps Vehicles/space maybe got something afterall.

early morning realisations prove to be somewhat unreliable... 1cf ~ 27liters.Originally posted by Gnusam Netor:

( faulty reasoning was: 3^4 = 81, but since this booring universe only has 3 dimensions, 4 is one too much. )

The human body has a density pretty close to that of water - 1kg/litre

If your weight is 200lbs, that converts to 91kg for a volume of 91 litres.

1 '^3 = 28.3 litres

91 litres is 3.2 '^3, approximate to 3 cubic feet.

I was tired ok? the time was 0530!!!

That lecture was so uncalled for. I now feel unjustly educated and when i feel unjustly educated i prepare longships for north sea travel, get it?

At almost 6'H x 2+'W x 9"D, I am closer to 8-9cf. Now, I need to lose some weight, but I'm not

This has made it crazy trying to create a robot from LBB8 where they claim 150

1 cubic foot = 12" x 12" x 12" = 1728 cubic inches.

One cubic inch is 2.54cm x 2.54cm x 2.54cm = 16.39 cm^3.

So a cubic foot is 1728 x 16.39 = 28,322 cm^3

Since 1000cm^3 is 1 litre, one cubic foot is 28.3 litres - or 28 if you want a rough estimate.

To get a rough estimate of your body volume in cuft, weigh yourself in pounds and divide by 62.

For more accuracy divide by 62.26

Although according to this site, 61-67 lbs/cuft is the usual range of human density.

from the site I quoted:

61-67 lbs/cu foot. This is the average density of a human body with breath exhaled (density drops to 56-62 lbs/cu foot if you inhale). Lower figures reflect relatively more body fat (which is lighter than bone and muscle).

Now look here Fritz, have you never realised stuff only to realise that your realisation was faulty and that was why 40 billion people (all living and all those who ever lived) apparently never realised it before you ? especially if you realise it at night? Have your synapses never fired a little on the random side?Originally posted by Fritz88:

Gnusam, where are you getting 1cf for a person? Are you only counting supermodels? (Oh... wait, you are in Sweden... well, that explains the supermodel calculations. )

Is Fritz perfect? surpassed only by God, hmm?

BTW, I think it is a great advantage if measuring units like meters or PSI or whatever is related to everyday stuff like a foot or the freezing point of water. So,

Of course when you have to convert between pressure and volume and distance and speed and, and so on the metric system rules, but the meter in itself (Kant style) is a lousy unit - inferior to the foot.

Supermodels? sorry they where all eaten by the polarbears yesterday...
