Quick Conversion Tips
Rounding for Simplicity
Use 2.2 for quick mental math. For example:- 50 kg ≈ 110 lbs
- 100 kg ≈ 220 lbs
- 50 kg ≈ 110 lbs
Estimate with Multiples of 10
Break down the weight into multiples of 10 kg:- 70 kg = 154 lbs (70 × 2.2)
- 4 kg = 8.8 lbs (4 × 2.2)
- Total: 154 + 8.8 = 162.8 lbs
- 70 kg = 154 lbs (70 × 2.2)
Use a Calculator for Precision
