Absolute Neutrophil Count (ANC) Unit Converter
Neutrophils are a type of white blood cell essential for fighting bacterial infections. The **Absolute Neutrophil Count (ANC)** measures the total number of neutrophils (including both segmented neutrophils and immature “bands”) in the blood.
Clinically, ANC is the gold standard for assessing a patient’s risk of infection, particularly during chemotherapy or in autoimmune disorders. A low ANC is known as **Neutropenia**. This converter facilitates switching between the International SI unit (× 109/L) and conventional absolute counts (cells/μL or cells/mm3).
SI Units / Standard
RecommendedSI Billions per liter (Numerically equivalent to thousands per microliter).
Absolute Count Equivalents
Clinical Context
Reference Range (Adult): Typically 1.5 – 8.0 × 109/L (1,500 – 8,000 cells/μL).
Neutropenia Severity Grading:
• Mild: 1.0 – 1.5 × 109/L
• Moderate: 0.5 – 1.0 × 109/L
• Severe (Agranulocytosis): < 0.5 × 109/L (High risk of serious infection)
Conversion Logic:
1 × 109/L (SI) = 1 × 103/μL = 1,000 cells/μL.

How to Use This Converter
Follow these steps to normalize ANC values across lab reports.
Enter Values
Input your laboratory results into the corresponding unit field (e.g., × 109/L). Use dot or comma for decimals.
Automatic Conversion
The calculator converts between SI shorthand (e.g., 1.5) and absolute cell counts (e.g., 1500).
Check Severity
Use the cells/μL output to compare against standard neutropenia guidelines (usually defined as <1500 or <500).
Reset
Use the Clear button to reset all fields.
Frequently Asked Questions
Yes. A result of “1.5” means 1.5 billion cells per liter, which equals 1,500 cells per microliter.
Yes. This tool converts units (e.g. 1.5 -> 1500). If you need to calculate ANC from WBC and % Neutrophils, use an ANC Calculator.
