App id: FLUID-09. Reference version 1.0.
How to fill it
Fill 1 values. The tool solves the rest.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
SG = ρ / ρ_refInputs
| Name | Unit |
|---|---|
| Specific gravity | 1 |
| Density | kg/m3 |
| Reference density (optional) | kg/m3 |
Outputs
| Name | Unit |

| Density (hero result) | kg/m3 |
| Specific gravity | 1 |
Diagnose
This tool does not attach diagnose observations.
Assumptions
- Leave reference density blank for 1000 kg/m³ (pure water at ~4 °C, not 998 at 20 °C).
Provenance
- SG is relative to the stated reference density.
