Quantity with Unit Parser
Parse a numeric value and its unit without performing a unit conversion.
Description
Parse a finite numeric value and preserve its attached unit without converting it.
Quantity with Unit Parser: Parse a finite numeric value and preserve its attached unit without converting it.
When to use Quantity with Unit Parser
Use this parser to convert a string in the named grammar into a structured value while making accepted syntax and failures explicit.
- Quantity
- Required string input.
- Number format
- Required string input.
How Quantity with Unit Parser works
Parse a finite numeric value and preserve its attached unit without converting it. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.1
- Value
- The resulting value returned as a number.
- Unit
- The resulting unit returned as a string.
Limitations and assumptions
- Parsing rules depend on locale, radix, encoding, escaping, duplicate fields, whitespace, overflow, rounding, time zone, units, and ambiguity policy. Successful parsing does not validate business meaning or make untrusted input safe.
- Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.
Alternative or Complementary approaches
Reject trailing or ambiguous content, preserve the original input, schema-validate the parsed value, and test malformed, boundary, and adversarial cases.
