Brix Calculator: Convert Brix to Specific Gravity and Back
Free Brix calculator converts Brix to specific gravity and back — 12 Brix ≈ SG 1.048 — with a wort correction factor for refractometer readings.

ℹ️ Refractometers are calibrated for sucrose — maltose wort reads about 4% high, so brewers divide by a wort correction factor (typically 1.02–1.06). Once fermentation starts, alcohol skews refractometer readings; use a hydrometer for final gravity.
