Unit standards, historical definitions and approximations can vary. Cooking volume-to-mass conversions depend on the ingredient; currencies require an exchange rate; sizing systems may be discrete; and logarithmic quantities such as decibels need purpose-built formulas rather than a linear scale.
For laboratory, medical, aviation, engineering or other safety-critical work, verify the definitions and standards that apply to your use case.
