Use cases
Brew Ratio — where it earns its place
On Brew Ratio —
Good coffee is mostly a ratio wearing a hat. Brew Ratio does the water-to-coffee arithmetic for whatever you are making — how many grams of grounds for the water you have, or the reverse — so the cup comes out the way it did the day you got it right. It computes and keeps nothing; the ritual stays yours. On this page: three concrete ways anyone who does this calculation more than once reaches for the Brew Ratio, and the signals that tell you it fits.
When the Brew Ratio earns its place
You come to the Brew Ratio the way you come to any well-made calculator: with numbers, a question, and no patience for a landing page. It gives you a result and forgets it. That is its whole personality.
Most tools in this category — web calculators festooned with ads, spreadsheet templates you paid for once and lost — solve a version of the same problem, then bill you monthly for the privilege of remembering it. The Brew Ratio takes the opposite bargain: one file, once, kept.
Three scenarios drawn from kitchen, food, and home
The everyday one: you open the Brew Ratio on a Tuesday morning, punch in the numbers, and close it. Two minutes. The record is more honest than the app that pinged you to remind you.
The specific one: — the workflow it names is the calculation that most needs a home outside a subscription. Some people use only the Brew Ratio. Some fold it into a Swiss Knife next to five others. Both are correct.
The out-of-band one: months later, you want to look back. The Brew Ratio still opens because it is a file. There is no login lapsed, no export deadline missed. The answer is where you left it.
Signals it fits anyone who does this calculation more than once
You want a calculation that behaves like a document, not a service. You are comfortable typing your own numbers in. You would rather own the file than rent the calculator. Weight in the knife: 1. Manual: no manual — the tool is its own instructions.
Signals it fits
- You do this calculation more than onceThe Brew Ratio pays back every time you don't have to reinvent the shape.
- You want it offline, on your own machineNo account, no cloud, no vendor between you and the arithmetic.
- You're comfortable with a hand-kept fileThe Brew Ratio is a document. It behaves like one.
Questions people ask
How much coffee do I use per litre of water?
That depends on your ratio, and the tool does the division for you: pick the ratio, enter your water or your coffee, and it computes the other side. Same numbers, same cup, every morning.
Is this a full replacement for web calculators festooned with ads?
For the working core of what most people use it for — yes. For enterprise features (team seats, integrations, auto-import), no. The Brew Ratio is deliberately smaller and more honest about its scope.
Who is the Brew Ratio not for?
Anyone who does this calculation more than once's opposite: a team that needs shared cloud state, or someone who wants automation over ownership. Use a SaaS for that; use this for the file.
A calculation that opens where you left it, on the machine you left it on.
