Gravity Converter

Convert wort and beer gravity between specific gravity, degrees Plato, degrees Brix, gravity points and degrees Oechsle.

Value

Unit

Degrees Plato: 12.4°P
Degrees Brix: 12.4°Bx
Gravity units (points): 50GU
Degrees Oechsle: 50°Oe

Brix here is the sugar-in-water scale. Refractometer readings of wort usually need a wort correction factor, and readings taken after fermentation starts need an alcohol correction.

How gravity units relate

Specific gravity compares the density of the wort with the density of water: 1.050 means the wort is 5% denser than water. Degrees Plato and Brix express the same thing as a percentage of sugar by weight, and gravity points and degrees Oechsle as the difference from water multiplied by 1000.

The conversion between specific gravity and degrees Plato or Brix is not linear, so the calculator uses polynomial approximations. As a rough guide, 1 °P is about 4 gravity points: 1.050 is about 12.4 °P, and 12 °P is about 1.048.

Frequently asked questions

What is the difference between Plato and Brix?

Both express the percentage of dissolved sugar by weight. Plato is used for wort and Brix for sugar solutions such as fruit juice; for brewing purposes the two are nearly the same.

What are gravity points?

Gravity points are the decimal part of the specific gravity multiplied by 1000: 1.050 is 50 points. They make gravity easy to add up and scale when you plan a recipe.

Can I convert refractometer readings with this tool?

It converts the Brix scale itself. Refractometers read wort slightly differently from sugar water, so many brewers apply a wort correction factor first, and readings taken after fermentation starts need a separate correction for alcohol.

Does temperature affect my hydrometer reading?

Yes. Hydrometers are calibrated at one temperature, often 20 °C (68 °F) or 15.6 °C (60 °F), and warmer samples read low. Cool the sample or apply the correction for your hydrometer before converting.
