From wikipedia:
One often hears the term being applied to the limits that the human body can withstand without losing conciousness, sometimes referred to as "blacking out", or g-loc (loc stands for loss of consciousness). A typical person can handle about 5 g (50 m/s²) before this occurs, but through the combination of special g-suits and efforts to strain muscles —both of which act to force blood back into the brain— modern pilots can typically handle 9 g (90 m/s²) sustained (for a period of time) or more. Resistance to "negative" or upward gees which drive blood to the head, is much less. This limit is typically in the -2 to -3 g (-20 to -30 m/s²) range. The vision goes red and is also referred to as a "red-out". This is probably due to capillaries in the eyes bursting under the increased blood pressure. Humans can survive about 20 to 40 g instantaneously (for a very short period of time). Any exposure to around 100 g or more, even if momentary, is likely to be lethal.

Won't a standard scale work, measuring weight as a function of time? That will relate how much the force of gravity is acting on the mass. If a 50 kg object is weighing in at 100 kg on the scale, then you have reached 2g's. I'm not an expert...but it makes sense to me.

A g force scale? A human, on earth, will accelerate upwards in free fall. In free fall you are weightless. Free fall is measured in rounded up to 10m/s^2. If you are trying to figure it out with earth's gravitational field pulling down on you, then you will accelerate downward in free fall.

From what i've got been informed they strengthen and can them in Iowa, yet i will't be rather specific as i've got by no ability seen a canned Yam. and that i by no ability stop to be surprised at what psychological info I learn from my contacts on Yahoo solutions. by ability of how, that's often been my existence long dream to confirm a yam.. Ahhh, possibly some day...

the force of gravity is not constant and differs depending on what planet you send a human being up from

I don't know any, but a person can only withstand 5gs for a few seconds before he/she blacks out.
