Red Blood Cell (RBC) Count Unit Converter
Red Blood Cells (RBCs), also known as erythrocytes, are responsible for transporting oxygen from the lungs to the body’s tissues. The RBC count is a standard component of a Complete Blood Count (CBC).
Clinically, abnormal RBC counts can indicate conditions such as anemia (low count) or polycythemia (high count). This converter facilitates switching between the international SI unit (× 1012/L) and the conventional unit (× 106/μL).

Clinical Context
Reference Ranges (Adults):
• Male: 4.5 – 5.9 × 1012/L.
• Female: 4.1 – 5.1 × 1012/L.
Conversion Logic:
1 × 1012/L = 1 × 106/μL.
1 × 106/μL = 1,000,000 cells/mm3.
