There are about 100 kcalories from ethanol in a standard drink of vodka.
A standard drink (depends on the country - but let's say the United States, for example) is a beverage that contains 0.6 fluid ounces of ethanol (this equates to one pint of a 5% ABV beer or a shot of 40% ABV spirit).
The alcohol in a standard drink is metabolized in about one hour.
You could make one weak drink from one fluid oz.
A standard drink is 0.6 ounces of pure alcohol, regardless of gender. The maximum recommended daily intake is two standard drinks for males, one for females (who tend to be smaller and who do not metabolize alcohol as efficiently as men due to lower enzyme levels).
The body can metabolize the alcohol contained in one standard drink in about one hour.

For a female one "standard drink" per day, for a male two per day. A standard drink is one 12-ounce beer, four ounces of wine, or one shot of liquor.
The amount of alcohol in a standard drink varies in different countries, from 6 grams in Austria to 19.75 grams in Japan. (Japan, as a country, is in serious denial about the extent of their drinking problems. Binge drinking is sort of a national sport.)In the United States, a standard drink (unit) of alcohol is any drink that contains about 14 grams of pure alcohol (about 0.6 fluid ounces or 1.2 tablespoons). In the US, a standard drink is calculated as roughly the amount of alcohol that can be metabolized by the human body in one hour. In other words, if you drank one unit per hour you could (at least in theory) continue to drink indefinitely without becoming intoxicated. In fact, metabolic rates vary among individuals and by gender, so this is not even an accurate approximation.

"Just as a body, though one, has many parts, but all its many parts form one body, so it is with Christ. For we were all baptized by one Spirit so as to form one body-whether Jews or Gentiles, slave or free -and we were all given the one Spirit to drink. Even so the body is not made up of one part but of many." 1 Corinthians 12:12-14
