Baker's Percentages
Baker's Percentages, a small reckoner that computes in your browser and stores nothing. No account, no cloud, no telemetry.
This is not a screenshot. It's the real tool, running right here: go on, put something in it.
Forged into a knife, this tool ages with use: the blades you reach for wear soft, entries you tend keep their bloom, and the years travel with the file through every reforge.
Serious bread recipes are written as percentages of the flour, which is elegant right up until you have 730 grams of flour and a recipe that assumes a round thousand. Baker's Percentages does the conversion both ways — recipe to percentages, percentages to real gram weights for whatever flour you actually have. It computes your formula and keeps nothing; the sourdough remembers enough for both of you.
Standing facts
- One HTML file. Opens in any modern browser, on any operating system.
- No account. No login, no sign-up, no e-mail wall.
- No cloud. Nothing leaves your browser: no server, no telemetry, no analytics.
- Yours forever. The file keeps working whether or not Offline.Ltd does.
- Ages with use. Entries you tend keep their bloom; the years travel with the file through every reforge.
In ten years
Baker's Percentages computes; it doesn't hoard. Open the file in 2036 and it will do the same arithmetic it does today, because the arithmetic is written into the file and nothing about it needs a server to agree.
If Offline.Ltd closes tomorrow, nothing on your machine notices. That isn't a marketing promise; it's simply what a file is.
Getting your data out
There is nothing locked in to get out: copy the numbers, or keep the file. Either way you owe no one a request form. No export queue, no "we'll e-mail you a link within 48 hours", no format that only one vendor can read.
Copy the file to a USB stick, a NAS, a folder your devices already sync. It runs on Windows, macOS, Linux, Android and iOS, online or off, because a browser is the only thing it ever needed.
Who else sees this
Nobody. Baker's Percentages works out its answer in your browser and forgets it the moment you close the tab: there is no store to breach, because nothing is stored. There is no account, no telemetry, no analytics, and no code in the file that opens a network connection, pull the cable and watch it carry on working. How privacy works across the Reckoners tools →
Questions people ask
What are baker's percentages and why do bakers use them?
Every ingredient is expressed as a percentage of the flour weight — flour is 100, water at 70 percent means 70 grams per 100 of flour. It makes any recipe scalable to any amount of flour, which is why bakers swear by it.
How do I scale a bread recipe to the flour I have on hand?
Enter the formula's percentages and your flour weight, and it computes the gram weight of everything else. The 730-gram bag stops being a problem and starts being a loaf.
Does this baking calculator save my recipes?
No — it computes and stores nothing. It is one HTML file running offline in your browser; your formula never leaves the page. Keep the recipe in your notebook, where bread recipes have always been safest.
