What the Alcohol Unit Calculator does
Alcohol Unit Calculator: calculates UK Alcohol Units and Alcohol (grams) from Drink Volume and Alcohol % (ABV). Example: drink volume 330 ml and alcohol % (ABV) 5 % gives UK alcohol units 1.6.
The Alcohol Unit Calculator takes Drink Volume and Alcohol % (ABV) and returns UK Alcohol Units and Alcohol (grams). Results refresh instantly, so trying variations costs nothing but a moment.
A single number is most useful as a trend over time rather than a one-off judgement. That is usually what brings someone starting a new plan here.
Your measurements stay on your device. Health numbers are nobody else’s business, including ours.
Further down the page: what each field expects, how the result is derived, and one example worked from the defaults.
What do the Alcohol Unit Calculator fields mean?
The Alcohol Unit Calculator uses 2 inputs. Every field is populated on load; treat those numbers as a template rather than a suggestion.
| Field | What to enter | Default |
|---|---|---|
| Drink Volume | measured in ml; accepts 10 to 2000 | 330 |
| Alcohol % (ABV) | measured in %; accepts 0.5 to 80 | 5 |
How does the Alcohol Unit Calculator work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same calculation.
The tool refuses to guess: if a value is missing or impossible, it says so.
Worked example
These are the values the Alcohol Unit Calculator loads by default, and the result it produces from them. This walkthrough uses the starting values, which means you can follow along without typing anything.
| Drink Volume | 330 ml |
|---|---|
| Alcohol % (ABV) | 5 % |
| UK Alcohol Units | 1.6 |
|---|---|
| Alcohol (grams) | 13.2 |
| What this means | This drink has about 1.6 UK units (13 g alcohol). Many guidelines suggest limiting weekly units: check local advice. |
How to use it
- Put Drink Volume in ml (10 to 2000).
- Key in Alcohol % (ABV) in % (0.5 to 80).
- You will see the result move while you are still editing: that is expected.
- The results panel then shows UK Alcohol Units, Alcohol (grams) and What this means.
- Share the link rather than a screenshot. It carries the values with it.
What this tool does not do
- This is a screening estimate, not a diagnosis.
- Body composition, ethnicity and age all shift what a "normal" result means for an individual.
- Results are informational: check anything consequential against a second source.
- Check that each figure is in the unit the label asks for; that is the most common source of a wrong result.
Frequently asked questions
Enter Drink Volume in ml and Alcohol % (ABV) in %. Units are printed on the form itself. Match them and no manual conversion is needed.
Drink Volume accepts 10 to 2000 ml. Values outside that range are rejected with a message naming the field, rather than producing something that looks valid but is not.
With the values loaded when the page opens, UK alcohol units comes out as 1.6. Change a value and the number is recomputed on the spot.
It is not stored or transmitted. The calculation happens locally and leaves no trace with us.
It is free to use, with no premium tier holding back the useful parts.
The arithmetic is correct; the model is a population approximation. Individual factors move the real answer, so treat the figure as context rather than a conclusion.
