How 42 g/L of hemoglobin converts to mmol/L
Hemoglobin is the oxygen-carrying protein in red blood cells, measured as part of a complete blood count (CBC). Hemoglobin is reported in g/dL on U.S. reports, in g/L on many European reports (g/L = 10 × g/dL), and occasionally in mmol/L in the Netherlands and parts of Scandinavia.
The conversion factor used here is 0.06206. Hemoglobin searches are usually in g/L (common on European CBC reports). 1 g/L = 0.06206 mmol/L (one tenth of the g/dL factor, since g/L = 10 × g/dL). Applied here: 42 g/L × 0.06206 = 2.607 mmol/L.
