Tool Categories
General Brewing Tools
Essential calculators for everyday brewing calculations:
Alcohol / Attenuation / Calories - Calculate alcohol content (ABV/ABW), attenuation levels, and nutritional information from your original and final gravity readings
Yeast Pitch Rate / Yeast Starter - Determine the optimal amount of yeast needed for your batch and calculate starter requirements for liquid yeast
Refractometer / Brix - Convert Brix readings to specific gravity and correct refractometer readings during fermentation
Gravity Correction / Boil Off - Adjust your wort gravity by calculating water additions or boil-off requirements
Hydrometer Temperature Correction - Correct hydrometer readings based on sample temperature for accurate gravity measurements
Carbonation - Calculate priming sugar amounts for bottle conditioning or pressure settings for force carbonation
Hop Freshness - Estimate hop alpha acid degradation over time based on storage conditions
Brewing Conversion Tools
Convert between different brewing measurement units:
Gravity Conversion - Convert between Specific Gravity, Plato, Brix, and other gravity units
Color Conversion - Convert beer color between SRM, EBC, and Lovibond scales
Unit Conversion Tools
General measurement conversions for brewing:
Volume Conversion - Convert between liters, gallons, quarts, and other volume units
Weight Conversion - Convert between kilograms, pounds, ounces, and other weight units
Temperature Conversion - Convert between Celsius, Fahrenheit, and Kelvin
Pressure Conversion - Convert between PSI, bar, kPa, and other pressure units
Mash Tools
Specialized calculators for mash temperature and calibration:
Strike Temperature Calculator - Calculate the water temperature needed to hit your target mash temperature
Rest Temperature Calculator - Determine infusion temperatures for multi-step mashes
Mash-Tun Calibration - Calculate your mash tun's heat loss coefficient for accurate strike temperature predictions
How to Use the Tools
Navigate to the Tools tab in Brewfather
Select the calculator you need from the organized categories
Enter your measurements or values
The tool will instantly calculate and display results
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.
