Where kg-to-lbs actually matters
Three situations dominate: gyms where the plates are in kg but the program is in lbs, airlines where the limit is one unit and your scale is the other, and fitness apps that record your bodyweight in a unit you don't use.
- • Use kg For: Metric gym plates (most of the world), EU airline baggage limits, Metric fitness apps, Scientific or medical records in kg
- • Use lbs For: US gym plates, US airline baggage limits, Imperial fitness apps, US bodyweight references
Rule of Thumb: Use 2.2 for conversation. Use 2.20462 for anything with a limit.
