Basophils (BASO) Unit Converter
Basophils are a type of granulocyte involved in allergic reactions and immune responses to parasites. They contain granules filled with histamine and heparin.
Basophil counts are typically reported as part of a Complete Blood Count (CBC) with differential. They can be expressed as a percentage or an absolute count. This calculator converts between the raw absolute count (cells/μL) and the standard clinical reporting units (K/μL or ×109/L).
Raw Count
AbsoluteActual number of cells per microliter. Equivalent to /mm³.
Standard / SI Units
SI Unit (G/L) and US K/μL are numerically identical.
Clinical Context
Reference Ranges (Adults):
• Absolute Count: 0 – 200 cells/μL (0 – 0.2 ×109/L).
• Percentage: 0% – 1% of total WBCs.
Basophilia (High Basophils):
Defined as an absolute count > 200 cells/μL.
• Allergic Reactions: Hypersensitivity, food allergies.
• Myeloproliferative Disorders: Chronic Myeloid Leukemia (CML), Polycythemia Vera. Basophilia is a hallmark of CML.
• Inflammation: Inflammatory Bowel Disease (IBD), Rheumatoid Arthritis.
Conversion Logic:
1 K/μL = 1000 cells/μL.
1 ×109/L = 1000 cells/μL.
Therefore: 0.1 K/μL = 0.1 ×109/L = 100 cells/μL.

How to Use This Converter
Follow these steps to normalize Basophil values.
Identify the Unit
Check your lab report. Raw counts are usually whole numbers (e.g., 50), while standard units are decimals (e.g., 0.05).
Enter Values
Input the number into the appropriate field. The calculator automatically converts across all fields.
Reset

Frequently Asked Questions
This is normal. Basophils are rare in the blood, so a count of zero is within the reference range for healthy adults.
Numerically, they are the same. G/L stands for Giga per Liter (10^9), and K/μL stands for Thousands per Microliter (10^3). The conversion factor between L and μL cancels out the difference between Giga and Kilo.
