How to calculate gravity converter
Method: Specific gravity and degrees Plato convert through standard brewing polynomial approximations
- Select the direction of conversion.
- Use a temperature-corrected gravity or Plato value.
- Apply the approximation and retain sensible precision.
Worked example
Using these planning inputs:
- Convert: sg
- Reading: 1.05
Degrees Plato: 12.39 °P
Reality check: Laboratory tables and instrument calibration can differ slightly; do not treat extra decimal places as extra accuracy.
Before you calculate
Use consistent units and the best measured inputs available. Real materials, equipment, site conditions and tolerances can change the result. Vaelden shows planning estimates; regulated, structural, electrical, plumbing, pressure and other safety-critical work still requires appropriate local compliance and professional advice.
