According to the World Health Organization, 50 milligrams of alcohol per 100 milliliters of blood, commonly written as a BAC of 0.05%, is a legal driving limit in many countries. However, this metric is often misunderstood, as its translation into physical effects can vary dramatically from person to person. The number itself represents a specific concentration of alcohol in the bloodstream, not an absolute quantity consumed.

Many people are confused by alcohol measurements; for example, asking "How much is 150 mg of alcohol?" often references a blood alcohol concentration (BAC) level of 150 mg/dL, a level associated with significant physical and mental impairment. This article clarifies this critical distinction and explains what this high level of intoxication means.
