Sorry for any inconvenience, and thank you for your support. We are looking forward to continuing our journey in the new year.
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.
