Aviation Context
US aircraft POH/AFMs use pounds for weight and balance. Many international operators use kilograms. The FAA uses standard passenger weights (170 lbs summer / 200 lbs winter including carry-on) for W&B calculations when actual weights are not available. Always use actual weights when possible.
