Calculation Formula

P = 1000 × (1 - (1.658 * SG^5 - 0.00506 * SG^4 + 0.00464 * SG^3 - 0.00145 * SG^2 + 0.00048 * SG - 0.000027) / SG^3)

Where:
P = Degrees Plato
SG = Specific Gravity (weight of liquid compared to weight of water at the same temperature)

Belgian Beer Gravity to Degrees Plato Conversion Calculator Calculator Usage Guide

Learn how to use the calculator to convert beer gravity to Plato for accurate brewing measurements

How to Use This Calculator

  1. Enter the Specific Gravity (SG) of your beer wort in the input field. This is typically measured using a hydrometer before and after fermentation.
  2. Click the Calculate button to convert the gravity to Degrees Plato.
  3. The result will be displayed in the Degrees Plato field, showing the sugar content of your wort.
  4. Use the Reset button to clear all inputs and start over.

Why Convert Gravity to Plato?

Specific gravity measurements can be affected by temperature, making direct comparisons difficult. Plato degrees provide a standardized way to measure extract potential regardless of temperature variations. This is particularly important in Belgian beer brewing, where precise measurements help achieve the characteristic high fermentation rates and complex flavors.

Example Calculation

If your pre-boil gravity is 1.050, enter this value and the calculator will show approximately 12.8°P. This indicates that your wort contains about 12.8% sugar by weight.

Important Notes

  • The calculator uses the standard beer gravity to Plato conversion formula developed by Tinseth and Young.
  • For the most accurate results, use a calibrated hydrometer and take readings at a consistent temperature (typically 60°F/15°C).
  • Remember that Plato is a measure of potential extract, not actual extract after fermentation is complete.
