For this case we must make a conversion from pounds to kilograms.
By definition we have to:
1 kg equals 2.20462 pounds. Making a rule of three we have:
2.20462 pounds ---------------> 1 kg
127 pounds -----------------------> x
Where "x" represents the amount of kg.

Thus, 127 pounds represent 57.61 kilograms.
Answer:
57.61 kilograms.
