What is a standard drink in Singapore?
HealthHub states that one standard alcoholic drink contains 10 grams of alcohol. It gives rough examples including a 330 ml regular beer at 5% ABV, 100 ml wine at 15% ABV, and a 30 ml shot of spirits at 40% ABV. Products and pours vary, so the label is more precise than the drink name alone.
How to calculate Singapore standard drinks from a label
First estimate pure alcohol in grams: volume in ml × ABV as a decimal × 0.789. Then divide the result by 10. For example, a 250 ml drink at 5% ABV contains about 9.9 g of pure alcohol, or about 1.0 Singapore standard drink.
Quick, label-based examples
| Example label | Approx. pure alcohol | Singapore standard drinks |
|---|---|---|
| 250 ml beer at 5% ABV | 9.9 g | 1.0 |
| 100 ml wine at 15% ABV | 11.8 g | 1.2 |
| 30 ml spirit at 40% ABV | 9.5 g | 0.9 |
These are arithmetic illustrations, not recommended amounts or a way to assess impairment. Use the product label for a more relevant result.

Alcohol and driving
Do not use a standard-drink count or any online BAC estimate to decide whether to drive, cycle, operate machinery, or make a medical or legal decision. Alcohol effects and measured BAC vary between people and situations. If alcohol is involved, arrange a sober way home before drinking.
