What is the SI unit for RBC?

The SI unit for Red Blood Cell (RBC) count is x 10⁹/L.

While RBC counts are often expressed as millions/uL in some contexts, the Système International (SI) unit provides a standardized measure for scientific and medical use. According to the provided reference, RBC counts, when expressed in SI units, are given as x 10⁹/L (per liter).

Here's a breakdown:

• RBC: Refers to Red Blood Cells, also known as erythrocytes. These cells are crucial for oxygen transport in the body.
• SI Unit: The International System of Units, a standardized system of measurement used globally in science and medicine.
• x 10⁹/L: This means "times ten to the power of nine per liter." It indicates the number of red blood cells present in one liter of blood, expressed in scientific notation, according to SI standards.
