FAQ

What formula does this use?

Pure alcohol (g) = volume (mL) ร— ABV (%) รท 100 ร— 0.8, using ethanolโ€™s specific gravity of approximately 0.8 g/mL.

Why 0.8?

Ethanol (alcohol) has a specific gravity of about 0.8 g/mL. This is the standard coefficient used by public health bodies like Japanโ€™s Ministry of Health for pure alcohol calculations.

What counts as "moderate drinking"?

Japanโ€™s Ministry of Health guideline suggests an average of about 20g of pure alcohol per day, though appropriate amounts vary by individual.
