Frequently Asked Questions
Why are alcohol units different in different countries?
Different countries have established their own standard drink definitions based on their drinking cultures, health policies, and regulatory frameworks. The US uses 14g, the UK uses 8g, and Australia uses 10g of pure alcohol as their standard units.
How accurate is this converter?
This converter uses internationally recognized conversion factors and is highly accurate for pure alcohol content calculations. However, actual drink sizes and alcohol percentages may vary, so always check product labels.
Can I use this for calculating BAC?
While this tool converts between alcohol units, calculating BAC requires additional factors like body weight, gender, and time. Use our dedicated BAC Calculator for blood alcohol content estimation.
What's the difference between grams and milliliters of alcohol?
Grams measure the weight of pure alcohol, while milliliters measure volume. Pure ethanol has a density of 0.789 g/mL, so 1mL of pure alcohol weighs about 0.789 grams.
How do I know how much alcohol is in my drink?
Check the alcohol by volume (ABV) percentage on the label and multiply by the volume. For example, a 12 oz beer at 5% ABV contains 0.6 oz of pure alcohol.
