## Tool Categories

### General Brewing Tools

Essential calculators for everyday brewing calculations:

* [**Alcohol / Attenuation / Calories**](https://docs.brewfather.app/tools/alcohol) - Calculate alcohol content (ABV/ABW), attenuation levels, and nutritional information from your original and final gravity readings
* [**Yeast Pitch Rate / Yeast Starter**](https://docs.brewfather.app/tools/yeast-calculator) - Determine the optimal amount of yeast needed for your batch and calculate starter requirements for liquid yeast
* [**Refractometer / Brix**](https://docs.brewfather.app/tools/refractometer) - Convert Brix readings to specific gravity and correct refractometer readings during fermentation
* [**Gravity Correction / Boil Off**](https://docs.brewfather.app/tools/gravity-correction) - Adjust your wort gravity by calculating water additions or boil-off requirements
* [**Hydrometer Temperature Correction**](https://docs.brewfather.app/tools/hydrometer-correction) - Correct hydrometer readings based on sample temperature for accurate gravity measurements
* [**Carbonation**](https://docs.brewfather.app/tools/carbonation) - Calculate priming sugar amounts for bottle conditioning or pressure settings for force carbonation
* [**Hop Freshness**](https://docs.brewfather.app/tools/hop-freshness) - Estimate hop alpha acid degradation over time based on storage conditions

### Brewing Conversion Tools

Convert between different brewing measurement units:

* [**Gravity Conversion**](https://docs.brewfather.app/tools/gravity-conversion) - Convert between Specific Gravity, Plato, Brix, and other gravity units
* [**Color Conversion**](https://docs.brewfather.app/tools/color-conversion) - Convert beer color between SRM, EBC, and Lovibond scales

### Unit Conversion Tools

General measurement conversions for brewing:

* [**Volume Conversion**](https://docs.brewfather.app/tools/volume-conversion) - Convert between liters, gallons, quarts, and other volume units
* [**Weight Conversion**](https://docs.brewfather.app/tools/weight-conversion) - Convert between kilograms, pounds, ounces, and other weight units
* [**Temperature Conversion**](https://docs.brewfather.app/tools/temperature-conversion) - Convert between Celsius, Fahrenheit, and Kelvin
* [**Pressure Conversion**](https://docs.brewfather.app/tools/pressure-conversion) - Convert between PSI, bar, kPa, and other pressure units

### Mash Tools

Specialized calculators for mash temperature and calibration:

* [**Strike Temperature Calculator**](https://docs.brewfather.app/tools/strike-temperature) - Calculate the water temperature needed to hit your target mash temperature
* [**Rest Temperature Calculator**](https://docs.brewfather.app/tools/rest-temperature) - Determine infusion temperatures for multi-step mashes
* [**Mash-Tun Calibration**](https://docs.brewfather.app/tools/mash-tun-calibration) - Calculate your mash tun's heat loss coefficient for accurate strike temperature predictions

## How to Use the Tools

1. Navigate to the **Tools** tab in Brewfather
2. Select the calculator you need from the organized categories
3. Enter your measurements or values
4. The tool will instantly calculate and display results
5. Many tools save your last entered values for convenience

## Tips for Best Results

* **Use consistent units** - Make sure your equipment profile and recipes use the same unit system as your measurements
* **Temperature matters** - Always temperature-correct hydrometer readings for accuracy
* **Save common values** - Many tools remember your last inputs between sessions
* **Cross-reference** - Use multiple tools together (e.g., temperature correction with gravity readings)

## Working with Your Settings

* Tools respect your global unit preferences from Settings
* The last values you enter are remembered for convenience
* All calculations use your preferred measurement system (Metric/Imperial/US)

## Mobile and Desktop

All tools are fully responsive and work on:

* Desktop web browsers
* Mobile web browsers
* iOS and Android apps
* Tablets and iPads

The interface adapts to your screen size for optimal usability whether you're in the brewery or at your computer.
