You're asking about a range, not a specific weight. Here's how to figure out the pounds for that range:

* 1 kilogram (kg) is equal to 2.20462 pounds (lbs).

To convert 10 kg to pounds:

* 10 kg * 2.20462 lbs/kg = 22.0462 lbs

To convert 20 kg to pounds:

* 20 kg * 2.20462 lbs/kg = 44.0924 lbs

Therefore, 10-20kg is approximately equal to 22.05 to 44.09 pounds.
