Mass is not force

Pounds (lb) and kilograms (kg) measure mass. Pound-force (lbf), by contrast, measures force; a mass-to-force calculation requires an acceleration such as gravity. Never interchange lb and lbf labels.

One international avoirdupois pound is defined as exactly 0.45359237 kilogram. Smaller displayed decimal counts are rounding choices, not new physical definitions.

Methodology: fixed SI definitions and standards-based factors. For safety-critical use, verify the required industry specification. Check definitions, conventions and sources.
