Calculate the exact amount of RO water needed to achieve your target specific gravity
Calculation Result
⚠️ Important: Measure specific gravity at 25°C (77°F) for accurate readings. Temperature affects density measurements.
Algorithm Used
This calculator uses the dilution formula: C₁V₁ = C₂V₂, where specific gravity is proportional to salinity concentration.
The calculation determines the volume of RO water needed: RO Volume = Current Volume × (Current SG - Target SG) / (Target SG - 1.000).
This assumes RO water has a specific gravity of 1.000 and accounts for the linear relationship between specific gravity and dissolved salt concentration in seawater.
