Unit Conversion Chain

Given a quantity expressed in one set of units with multiple conversion factors (e.g., conductors, distance, weight per unit length, and mass ratio), chain together a series of unit conversions to obtain the final result in a target unit.

✓ All 2 test cases pass.

Inputs

Number of conductors

Count of parallel conductors

Distance in miles

Length of conductor run

Weight per 1000 feet (lb)

Linear mass density

Conversion factor (lb to kg)

Mass conversion ratio
