Brix to PPM Converter
Refractometers read Brix (percent sugar); some specs want PPM. 12 °Bx orange juice is about 120,000 PPM dissolved sugar — multiply Brix by 10,000.

Refractometers read Brix (percent sugar); some specs want PPM. 12 °Bx orange juice is about 120,000 PPM dissolved sugar — multiply Brix by 10,000.
How to use this calculator
- Enter °Brix.
- Multiply by 10,000.
- Read PPM sugar.
The formula
1 °Bx ≈ 1% w/w sugar ≈ 10,000 PPM (approximate, density-dependent).
What the units mean
PPM (parts per million) — one part of solute per million parts of the total mixture. The workhorse unit for trace concentrations in water, air, and food.
Worked example
Grape must at 22 °Bx → ~220,000 PPM sugar.
Quick reference
| Brix | ≈ PPM sugar |
|---|---|
| 10 | 100,000 |
| 12 | 120,000 |
| 22 | 220,000 |
Approximate.
Where you will actually use this
Connects field refractometer readings with lab-style units.
- Juice QC
- Winemaking
- Beverage formulation
Mistakes that give wrong answers
- Brix measures all dissolved solids, not just sugar
- Temperature correction on refractometers
Key takeaways
- Formula: PPM ≈ °Brix × 10,000
- Remember: Approximate.
- Watch out for: Brix measures all dissolved solids, not just sugar
- Next step: run your own numbers in the calculator above, then verify with a measurement — calculated values are only as good as the inputs.
