Eosinophils (Absolute Count) Unit Converter
Eosinophils are granulocytes that modulate immune responses, particularly in defense against parasites and allergic inflammation. The Absolute Eosinophil Count (AEC) measures the exact number of these cells per unit volume of blood and is the only reliable metric for assessing clinical significance, as the percentage value is highly dependent on the total WBC count.
An elevated AEC (Eosinophilia) is classically associated with parasitic infections, drug reactions, and chronic allergic diseases like severe asthma. Low counts are typically non-specific but may occur during acute infection (due to steroid release) or chronic stress. This converter ensures accurate switching between the standard cell-count units (cells/µL) and the International SI unit (10⁹/L).

Clinical Context
Reference Range: The normal AEC is typically 50 – 500 cells/µL (0.05 – 0.5 × 10⁹/L).
Levels > 500 cells/µL define eosinophilia, which is classified as mild (500–1500), moderate (1500–5000), or severe (> 5000 cells/µL). Severe, sustained eosinophilia can lead to multisystem organ damage (e.g., Löffler syndrome). The conversion logic is: 1 × 10⁹/L = 1000 cells/µL.

Frequently Asked Questions & Tips
Yes. Microliter (µL) is exactly equivalent to cubic millimeter (mm³).
The percentage is relative. The Absolute Count is required to know the actual burden of eosinophils, especially when Total WBC is very low or very high.
