Hemoglobin unit converter
Hemoglobin (haemoglobin) is printed as g/dL in the United States, g/L in many other countries and mmol/L in a few. The digits look very different, which is why the unit matters. Enter the number and its unit to see it written in the others.
Enter the number exactly as printed on your report.
This tool only changes the unit a number is written in. It does not say what any result means. Your laboratory’s own units and ranges apply.
How the units relate
- 1 g/dL = 10 g/L
- 1 mmol/L = 16.114 g/L (hemoglobin counted per haem group)
Worked examples are in Hemoglobin units explained.
Questions
Does this tell me what my result means?
No. It only changes the unit a number is written in. Laboratories publish their own reference ranges in their own units, and what a result means is a question for your doctor.
Does it store what I type?
No. The number stays in your browser and is not sent anywhere.
Which unit should I write down?
The one printed on your report, every time, next to the number. FerroLady keeps each result in the unit you entered and never rewrites it.
