# Coffee brewing ratio

Canonical page: https://nepocore.com/tools/coffee-ratio/

Calculate coffee or water amounts from your chosen brewing ratio. This browser tool shows the inputs, assumptions and resulting output so you can use it for a specific everyday task.

## How to use it

1. Enter your own values or choose a supported file.
2. Adjust the options and run the tool.
3. Review the result, then copy, export or save it when available.

## Example

Use a 1:16 coffee-to-water ratio to calculate coffee for 320 g of water.

## Limits and checks

Ratios are by mass. Taste and brew method are personal, so this calculator uses the ratio you enter rather than declaring one universal recipe.

## Access and processing

Free to use without an account. Interactive processing requires JavaScript in a modern browser. Input is processed in the browser rather than sent to a processing server. Optional browser storage is not a synchronized account.
