The amount of an alcoholic beverage needed to consume one’s bodyweight in alcohol

The amount of alcohol needed in order to consume your own body weight can be denoted as the variable W. The value of W can be calculated using the formula


Where p is the density of alcohol and m is your mass. The density of alcohol under room conditions is 789g/L (meaning that 1 litre of alcohol weighs 789g, or 0.789kg). The mass of an average adult male, according to my highly reliable source Yahoo! Answers, is 86.6kg. Using this data, the equation becomes


Meaning that for an average adult male to consume his own bodyweight in alcohol, he must drink 109.76L of pure alcohol. Of course, most people do not take their alcohol pure, but instead enjoy it as a solution of alcohol, water, and other substances. So, to calculate the number of servings of your favourite alcoholic beverage you would require in order to drink your own bodyweight in alcohol, the following equation can be used

Where n is the number of bottles require, v is the volume of each bottle, c is the concentration of alcohol and W has the value calculated previously.

Let us take the example of one of Australia’s most popular beverages, Carlton Draught. How much of this beer would be needed in order to drink your own bodyweight in alcohol? Well, if we assume you are an average adult male we can use the W value previously calculated (109.76L). Let us assume you are drink 375mL stubbies or cans. This gives us our volume (v). Finally, the concentration (c) of alcohol in Carlton Draught is 4.6% alcohol per volume. Using these values, we get the equation



Carlton Draught, like most beer, is often sold in six-packs, as well as slabs of 24 bottles. 732 bottles makes up 30 slabs and 2 six-packs.

The LD50 of alcohol is 7g/kg, meaning that consuming 7 grams of alcohol per kilogram of body mass will result in death by toxicity 50% of the time. Therefore 606.2g of alcohol has a 50% of killing an average adult male of 86.6kg. Obviously, this means that consuming your own bodyweight in alcohol would be likely to kill you many times over (roughly 143 times). This only takes into account death caused by the toxicity of alcohol. Most alcohol-related deaths are caused by the psychological effects of alcohol, such as impaired judgement and decreased reaction time. These will come into effect long before the toxicity does, so any attempt at this feat would be extremely likely to result in death before any significant progress is made. As such, any person who would undertake such a suicidal task would certainly be a fucking legend advised not to.
