Mean Corpuscular Hemoglobin Calculator

About this calculator

Mean corpuscular hemoglobin (MCH) is calculated as hemoglobin concentration divided by red blood cell count, multiplied by 10, and expressed in picograms (pg) per red cell — it tells you the average amount of hemoglobin packed into a single red blood cell. MCH is one of three standard red-cell indices reported on a complete blood count (CBC), alongside mean corpuscular volume (MCV), which measures cell size, and mean corpuscular hemoglobin concentration (MCHC), which measures hemoglobin density relative to cell volume.

Hematologists and primary care physicians use MCH together with MCV to help classify anemia — a low MCH paired with a low MCV typically points toward microcytic, hypochromic anemia such as iron deficiency or thalassemia, while a high MCH paired with a high MCV is more consistent with macrocytic anemia from causes like vitamin B12 or folate deficiency. Lab technicians report it automatically as part of routine bloodwork, and clinicians reference it when interpreting CBC panels alongside a patient’s symptoms and history.

This calculator takes your hemoglobin level and red blood cell count and returns the corresponding MCH value in picograms, for educational reference alongside your lab results.
