About this calculator
Conversions inside one dimension (for example mg to µg, or mmol/L to mol/L) are pure factor conversions. Conversions between dimensions need additional physical data:
- Amount of substance ↔ mass requires the molecular weight (g/mol).
- Molar concentration ↔ mass concentration requires the molecular weight.
- Mass ↔ volume requires a density (g/mL).
No density is ever assumed — not even that of water. If the required value is missing, the converter refuses the conversion and says what it needs.
LabCalc is provided as a calculation aid. Users remain responsible for verifying calculations, units, chemical compatibility, experimental procedures and applicable safety requirements before laboratory use.
