Frequently Asked Questions

Find Quick Answers

What is UCUM and why is validation important?

UCUM (Unified Code for Units of Measure) is a standard for representing units in healthcare and science. Validation ensures unit codes are syntactically correct and semantically valid, preventing errors in medical calculations and data exchange.

What types of UCUM expressions can this validator check?

The validator checks simple units (mg, mL), compound units (mg/dL, cm^2), and expressions with operators (mg/kg/d, m/s^2). It validates syntax, base unit existence, and proper use of prefixes, exponents, and operators.

Does this tool store or transmit my unit data?

No, all validation happens entirely in your browser. No data is sent to any server, ensuring complete privacy for sensitive medical or research unit codes.
