Methods & limits
Every result traces back to one set of unit definitions.
Unit Lab handles defined, verifiable numeric relationships. It states when values use mainland-China jin or mu, decimal, or binary units so context does not silently change the answer.
Common base
Each category converts to one base unit, then to the target. This avoids maintaining every pair separately and reduces errors.
Display precision
Results display up to 12 significant digits. Display rounding does not change the conversion, but real work must follow the precision of its measurement and use case.
Definitions shown
Jin is 500 g, mu is 2000/3 m², GB scales by 1000, and GiB by 1024.
Scope
Useful for estimates and reference checks, but not a substitute for metrology, engineering review, laboratory records, or trade settlement.
