To convert a weight in pounds to kilograms, you multiply the number of pounds by the conversion factor (0.453592):
   Weight in kilograms=Weight in pounds×0.453592
Performing the Calculation:
Given the weight is 160 pounds, we will apply the formula:
    Weight in kilograms=160×0.453592
Now, perform the multiplication:
160×0.453592=72.57472 kg
Rounding to Two Decimal Places:
Typically, we round the result to two decimal places for convenience (unless more precision is needed):
72.57472 kg ≈ 72.57 kg 72.57472 kg≈72.57 kg
