These numbers refer to a person's blood alcohol concentration (BAC).

As such somebody consuming large quantities of alcohol can still be unfit to drive the next morning.

The human body can only process about one standard drink per hour, and alcohol concentration does not peak until 30 to 60 minutes after your last drink.

Body sizeA smaller person will have a higher BAC than a larger person because

the alcohol is concentrated in a smaller body mass.

Empty stomachSomeone with an empty stomach will reach a higher BAC sooner than someone who has just eaten a meal. Food in the stomach

slows down the rate at which alcohol passes into the bloodstream.

Body fatPeople with a lot of body fat tend to have a higher BAC. Alcohol is not absorbed into fatty tissue, so the alcohol is concentrated in a smaller

body mass.

SexAfter consuming the same amount of alcohol, a female will almost

always have a higher BAC than a male. http://www.mydr.com.au/addictions/blood-alcohol-concentration-bac
