ABV Calculator: OG to FG with Hydrometer Adjustment
For a common beer estimate, subtract final gravity from original gravity and multiply by 131.25. An OG of 1.050 and FG of 1.010 gives approximately 5.25% ABV.
Use calculator →Interactive toolBitterness Ratio (BU:GU) Calculator
BU:GU is IBU divided by original gravity points. At 30 IBU and OG 1.050, the calculation is 30 ÷ 50 = 0.60. Gravity units here are not ABV.
Use calculator →Interactive toolHop Substitution Finder: Replace Any Variety
Replacement weight = original weight × original alpha-acid percentage ÷ replacement alpha-acid percentage. Replacing 30 g of 6% hops with 9% hops gives 20 g as a starting estimate.
Use calculator →Interactive toolMastering Wort Dilution with Dilution & Gravity Calculator
For unfermented wort, final volume ≈ current volume × current gravity points ÷ target gravity points. Diluting 20 L at 1.060 to 1.050 requires about 4 L of water, giving 24 L total.
Use calculator →Interactive toolOriginal Gravity (OG) Calculator by Grain Bill
Wort gravity depends on grain potential, how much extract reaches your chosen measurement point and wort volume. Here, 5 kg of grain at 37 PPG, 75% recovery and 20 L gives approximately SG 1.058.
Use calculator →Interactive toolPre-Boil Gravity Calculator + Adjustments
If extract is retained while water evaporates, gravity points rise as volume falls. For 25 L at 1.040 reduced to 20 L, the estimate is 50 points, or SG 1.050.

Read guide →Interactive toolCocktail ABV calculator with ice dilution
Add up the alcohol in each ingredient (volume × ABV), divide by the total volume, then divide again by 1 plus the dilution share. 50 mL at 40%, 25 mL at 20% and 25 mL of juice give 25% before ice and 20% after 25% dilution.
Use calculator →Interactive toolABV calculator from sugar, honey and juice
Add up the dissolved sugar, find the gravity at which that sugar in your total volume matches its °Brix, then apply (OG − FG) × 131.25. 1.5 kg of honey made up to 4.5 L gives about 1.106 and 13.9% potential ABV if it ferments to 1.000.
Use calculator →Interactive toolBrewhouse and mash efficiency calculator
Efficiency = measured gravity points × US gallons ÷ (pounds of grain × PPG). 5 kg of grain at 37 PPG that gives 25 L at 1.044 has recovered about 71% of its potential.

Use calculator →Interactive toolBeer calorie and carb calculator
Calories per 100 mL ≈ 6.9 × alcohol by weight + 4 × (real extract − 0.1). A beer from 1.050 to 1.010 works out at about 162 kcal and 15 g of carbohydrate per 355 mL (12 US fl oz). It is an estimate, not a nutrition label.
