If an escalator weighs 5,700 kilograms, what is its weight in US customary units?

To convert the weight of the escalator from kilograms to pounds, you can use the conversion factor where 1 kilogram is approximately equal to 2.20462 pounds.

Starting with the weight of the escalator, which is 5,700 kilograms, you multiply this by the conversion factor:

5,700 kg × 2.20462 lbs/kg = 12,566.34 lbs.

When rounding to the nearest whole number, this equates to approximately 12,566 lbs.

Among the choices given, the option that is closest to this calculated weight is 12,540 lbs, which is why this choice aligns perfectly with the accurately converted weight from kilograms to pounds. This demonstrates how weight conversions are critical for understanding measurements in different unit systems, particularly in practical applications like understanding the weight of heavy machinery or equipment in engineering contexts.
