Why Do Some Countries Use Pounds While Others Use Kilograms?

- Pounds (lbs) are part of the Imperial system, mainly used in the United States and a few other places like Liberia and Myanmar.

How to Quickly Estimate Conversions
If you don’t have a calculator handy, here are a few mental math tricks:
- Divide by 2 and Subtract 10%
- Example:
- 166 lbs ÷ 2 = 83
- Subtract 10% of 83 (which is 8.3)
- 83 – 8.3 = 74.7 kg (which is pretty close to 75.3 kg!)
- Example:
- Use a Simple Ratio
- 1 lb ≈ 0.45 kg
- So, multiply by 0.45:
- 166 × 0.45 = 74.7 kg (again, close enough!)
- Round It for Everyday Use
- For quick estimates, just remember:
- 100 lbs ≈ 45 kg
- 50 lbs ≈ 23 kg
- 10 lbs ≈ 4.5 kg
- For quick estimates, just remember:
Using this method:
- 160 lbs ≈ 72 kg
- 6 lbs ≈ 2.7 kg
- Total: 75 kg (which is quite close to 75.3 kg!)
