Methodology
For factor-based categories, values pass through the configured base unit: base value = input value × source factor, then output value = base value ÷ target factor.

Quick Reference Table
| Unit | Converted to kg/m³ | kg/m³ converted to unit |
|---|---|---|
| g/cm³ | 1 g/cm³ = 1000 kg/m³ | 1 kg/m³ = 0.001 g/cm³ |
| lb/ft³ | 1 lb/ft³ = 16.0185 kg/m³ | 1 kg/m³ = 0.062428 lb/ft³ |
| lb/US gal | 1 lb/US gal = 119.8264 kg/m³ | 1 kg/m³ = 0.0083454 lb/US gal |
01
Engineering Basis
Assumptions
- Convert only between units in the same physical quantity family and with the same declared concentration or operating basis.
Scope / Limitations
- The converter normalizes units; it does not validate source data, infer a process basis, or replace the assumptions of a downstream model.
02
Engineering Path
Upstream Context
- Declared value and source unit Use the unit stated on the sample record, supplier sheet, or design note.
Current Tool Decision
- Density Unit Converter Convert within this quantity family while preserving the declared engineering basis.
Downstream Engineering Step
- Chemical Feed & Storage Designer Use the normalized value in the relevant engineering calculation and verify its basis.
- GAC Breakthrough & Bed-Life Designer Use the normalized value in the relevant engineering calculation and verify its basis.
- Water Treatment Residuals & Sludge Designer Use the normalized value in the relevant engineering calculation and verify its basis.
