I had a 1.5 liter bottle of white zinfandel 9% alcohol by volume of wine. I finished drinking about 9pm on Saturday night. I am a 270 lb male. How do I calculate the amount of alcohol consumed in mg/kg. I do random EtG testing and also would like your opinion on the shortest amount of time with this volume of consumption that I could pass if tested? I have seen charts that report as little as 24 hours in studies is this realistic?

Thanks for any info.

It should be out of your system within 6 hours, sometimes it does take up to 24 hours, seldom longer than that, so yes it is realistic.

Here is a calculator chart for future reference...

At 9% abv you consumed the equivalent of 7.6 standard drinks (US) or .87 grams of alcohol per kilogram of body weight. (.87 g/kg).

Not sure what chart you saw, but the EtG from that volume of alcohol would not be eliminated within 24 hours. More likely time span would be 72 (range 50-78) hours. Have noted a number of people passing at low end of this range even following greater consumption but it isn't wise to depend on that result.

Thank you, will you explain how you came up with these numbers for me. Mostly the conversion to standard and how you got to .87 grams. Thanks again

Sure. The volume to standard drinks (US) is simple when you have a fixed amount (1.5 liter is a 50.7 oz bottle) These full measures, pints, half-pint, fifth, are all standard. Here is a calculator that allows you to simply select and it converts: Drink Calculator (http://rethinkingdrinking.niaaa.nih.gov/ToolsResources/DrinkSizeCalculator.asp)

Each drink (US) contains 14 g of pure alcohol (PA). That is all that matters in the calculation. Multiply the number of drinks by 14 and you have total PA consumed in grams [106.4] .

Convert your weight in pounds [270] to kilograms [122.7] and then divide total PA by weight. 106.4 / 122.7 = .867
