Rounding: Internal floating-point calculations run in 64-bit IEEE-754 double precision; display values round to 2–4 decimal places.

Worked Example: Brix / Plato ↔ Specific Gravity Worked Example

Convert °Brix / °Plato into Specific Gravity (SG), g/L sugar, and potential wine/beer ABV %.

  1. Enter the input measurement, system configuration, or astronomical parameter.
  2. Apply the standard conversion or analytical equation: SG = 1 + (Brix / (258.6 − 0.8796 × Brix)); Sugar_g_L = Brix × 10 × SG; Potential_ABV% ≈ (SG − 1) × 131.25.
  3. Inspect the primary metric, secondary equivalents, and 3 real-time SVG graphs.
Result: Computes Brix / Plato ↔ Specific Gravity via SG = 1 + (Brix / (258.6 − 0.8796 × Brix)); Sugar_g_L = Brix × 10 × SG; Potential_ABV% ≈ (SG − 1) × 131.25.

Degrees Brix (°Bx) / Plato (°P) ↔ Specific Gravity (SG) & Potential Alcohol Converter: inputs, method, and how to read the result

Convert °Brix / °Plato into Specific Gravity (SG), g/L sugar, and potential wine/beer ABV %.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Degrees Brix Or Plato: Sugar concentration in Degrees Brix (°Bx) or Plato (°P) (1 g sucrose per 100 g solution).

What the calculation includes

With the default values shown, Solution Specific Gravity (SG @ 20°C) is 1.092 SG. The calculation follows Brix / Plato ↔ Specific Gravity Formula; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Degrees Brix Or Plato from 22 °Bx / °P to 24.2 °Bx / °P changes Solution Specific Gravity (SG @ 20°C) from 1.092 SG to 1.102 SG. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses official NIST Special Publication 811, IEEE/RFC systems engineering, APA psychometric, and USNO astronomical formulas.
  • Empirical metallurgy and calendar conversions represent standard reference-condition approximations.

Scope: Global NIST, IEEE, APA & Astronomical Standard Check the assumptions and limitations against your situation before relying on the estimate.
