How to use it
- Measure the inputs in the units shown. Keep a note of your original recipe.
- Change the relevant input and calculate. Compare the answer with the worked example below.
- Use the output within the stated limits; reset to restore the example inputs.
Worked example
18 g in / 36 g out scaled to 20 g in targets 40 g out.
Assumptions and limits
Does not determine basket capacity, grind, pressure or time. Follow the basket specification; do not assume shot time scales with dose.
Questions
What does this result establish?
Keep the beverage-to-dose ratio while changing the dose: new yield = old yield × new dose / old dose. It provides the stated arithmetic or random ordering; it is not a taste or equipment certification.
What measurements should I use?
Original dose (g); Original beverage yield (g); New basket dose (g). Keep the units consistent rather than copying a number from a differently labelled recipe.
Why is an input rejected?
Blank, non-finite, negative or out-of-domain measurements cannot produce a valid answer. Each field has a bounded range. Incompatible combinations show an explanation instead of retaining a previous result.
Can I use this without an account?
Yes. Once this page and its modules load, the calculation runs locally without accounts, external APIs or input storage. Reloading restores the defaults.
