Hemoglobin monomer is the protein molecule in red blood cells that carries oxygen from the lungs to the body's tissues and returns carbon dioxide from the tissues back to the lungs. Hemoglobin is made up of four protein molecules (globulin chains) that are connected together.

This calculator calculates the hemoglobin monomer in µmol/l, g/l, g/dl, g/100ml, g%, mg/ml using mmol/l values.
