This online tool, from Intoximeters, calculates your blood alcohol level based on number and type of drink, your weight, gender and number of hours since imbibing. This isn’t a license to drink and drive—NEVER DO THAT—but rather a fun experiment while drinking with friends. The are no guarantees that this is accurate, so don’t email me with a sob story about how you got a DUI. Just don’t drink and drive. Play with this at home.
