A "dram" is a small unit of measurement commonly used to quantify liquids, particularly in the context of spirits like whiskey. In the United States, a dram is typically equal to 1/8 of a fluid ounce, or about 3.7 milliliters. This measurement is often used in bars and restaurants to serve a modest amount of alcohol, allowing patrons to enjoy a taste without consuming a full serving. In addition to its use in measuring liquids, the term "dram" can also refer to a small amount of something, often in a more informal context. For example, one might say they have a "dram of luck" or a "dram of kindness." The word has its origins in the Greek word "drakhma," which was a unit of weight and currency.
