Packing Weight Allowance Calculator
Check how much weight remains in your baggage allowance after packing. Shows remaining kg and lbs.
How to use this tool
- Enter your airline's checked baggage weight limit in kg.
- Enter your bag's current packed weight in kg.
- The calculator shows remaining allowance in both kg and lbs and the percentage used.
Check how much of your baggage weight allowance you have left before heading to the airport.
Formula
Remaining (kg) = Allowance (kg) − Packed weight (kg)
Remaining (lbs) = Remaining (kg) × 2.20462
Allowance used (%) = Packed weight ÷ Allowance × 100
How it works
This calculator subtracts the current packed bag weight from the airline baggage allowance to reveal how much spare capacity remains, expressed in both kilograms and pounds. The kg-to-lbs conversion uses the exact factor 2.20462. Percentage utilisation is computed to help travellers quickly judge how close they are to the limit. Accuracy depends on the user entering the correct allowance for their specific ticket and fare class, as allowances vary by airline, route, and booking class.
Worked example
Worked example
- Allowance = 23 kg; packed bag weight = 15 kg.
- Remaining = 23 − 15 = 8 kg.
- Remaining in lbs = 8 × 2.20462 = 17.64 lbs.
- Allowance used = 15 ÷ 23 × 100 = 65.22%.
Remaining allowance = 8.00 kg (17.64 lbs); allowance used = 65.22%
