Gravity Unit Conversion

Convert specific gravity, gravity points, degrees Plato and Brix instantly.

Gravity in Specific Gravity

Enter a value in any scale — the other three update live. SGP = gravity points, thousandths of SG above 1.000.

Brix is treated as a pure sucrose scale, exactly like the app — no wort correction factor is applied. For refractometer readings during fermentation, use the Brewfather app's refractometer correction.

How this calculator works

Brewers use several gravity scales for the same underlying measurement: density, points, Plato and Brix.

The converter normalizes the entered value and then displays the equivalent value on the other supported scales.

Plato and Brix are close for normal wort readings, but they are not identical at every gravity.

Worth knowing

Brix is a refractometer scale; fermenting beer still needs alcohol correction before it can be read as final gravity.
Round trips between scales may not land on the exact original display value because each scale has its own rounding behavior.
