Practical tools for measured work
Alcohol dose and peak-model scenarios
Calculate ethanol dose and two illustrative Widmark peak scenarios. No present-BAC measurement or driving clearance.
How it works
Ethanol dose = drink mL × ABV fraction × 0.789 g/mL. An illustrative Widmark peak is dose divided by body mass and distribution factor. Two published example factors are displayed as scenarios; they are not individual confidence bounds.
Before using the result
- Check the selected mode, units and input values before using the result.
- Read the assumptions and rounding rules; compare the worked example with your intended calculation.
- A numerical result does not supply missing context or change the stated limitations.
Limitations
Not a measurement of your present BAC. Absorption, food, drinking pattern, body composition and elimination vary. No sober-time estimate, legal-limit comparison or driving clearance is provided. Do not use a calculated value to decide whether to drive or operate equipment. Mixed drink strengths require separate dose accounting.
Frequently asked questions
What should I verify before using this result?
Check the input values, units, dates and assumptions. Compare the method and its stated limits with the source relevant to your task.
Why might the finished result differ?
Results depend on the entered data and the model’s assumptions. Rounding, changing conditions or omitted factors can affect the comparison. Read the limitations before using the result.
