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.
Singapore health information
HealthHub's adult dietary guidance says adults who choose to drink should keep to one standard drink for women and two for men. It also states that people who do not drink should not be encouraged to start. This is educational health guidance, not a way to assess impairment or decide whether to drive.

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.
