BruCalc is an offline brewing calculator built for practical day-to-day brewery work. It brings common brewhouse, hop, yeast, cellar, water, and conversion calculations into one streamlined app designed around real brewing measurements. Calculators include: • Strike / Mash Water • Theoretical Yield • Brewhouse Efficiency • Kettle Addition Scaler • Sugar Gravity Adjustment • Hop Addition → IBU • IBU → Hop Addition • Dry-Hop Scaler • Pitch Rate • Carbonation • Attenuation & ABV • Sugar Addition • Liquor Back • Spirit Dilution • Beer Calories • Salt Addition • Volume Conversion • Weight Conversion • SG ↔ Plato • °F ↔ °C • Hydrometer Correction BruCalc also includes a read-only Formula Reference so you can review the equations, variables, units, assumptions, and methods used throughout the app. Designed for brewery-scale measurements, BruCalc supports units including bbl, gal, L, hL, lb, oz, kg, g, specific gravity, degrees Plato, IBU, ppm, psi, bar, kPa, and cells/mL/°P. Key features: • Works offline • No account required • Fast, practical brewery calculations • Transparent formulas and assumptions • Imperial and metric unit support • Built for brewhouse, cellar, yeast, hop, and water calculations BruCalc is intended as a brewing reference and calculation tool. Users remain responsible for verifying results and determining whether calculations are appropriate for their own equipment, ingredients, processes, and operating procedures.
