Scope and limitations
Weights can use any common scale but their total cannot be zero. Uses real-number arithmetic and rounds display values without changing the entered inputs. Check important results independently.
Common questions
Can I use different units?
Use consistent units unless this page is a unit converter. The result follows the units implied by the inputs.
Are results exact?
Displayed values may be rounded. Keep extra precision for important follow-up calculations.
Methods & verification
Formulas use standard mathematical definitions and fixed unit factors where applicable. See our methodology for numerical conventions, rounding, privacy, and limitations.
