Hemoglobin Unit Converter

The Hemoglobin Unit Converter translates hemoglobin values between g/dL and mmol/L. It uses a fixed conversion factor of 0.620 to switch from g/dL to mmol/L, and the inverse for the opposite direction. The tool is designed for clinicians, nurses, students, and laboratory staff who need quick reconciliation of results across reporting standards. Conceptually, a value such as 13 g/dL equals 8.06 mmol/L (13 × 0.620), enabling direct comparison with reports that present results in mmol/L. The system supports bidirectional conversion with configurable decimal precision, defaulting to two decimals. This enables consistent documentation in patient charts, research notes, and education materials. Unique value lies in its domain-aligned factor, immediate feedback, and a minimal UI footprint that reduces transcription errors and accelerates data interpretation. Use cases include adjusting a chart that lists Hb in mmol/L to present values in g/dL for a clinician accustomed to that unit, or auditing lab reports to ensure uniform unit usage across a documentation workflow.
