Newton/metre (N/m) is NOT a correct unit of ‘power’.

Power is defined as the rate of doing work or transferring energy. Its standard unit in the SI system is the Watt (W).

Work is Force x Distance, measured in Joules (J) or Newton-metres (N.m). Power = Work/Time. So, Joule/second (J/s) and (Newton-metre)/second (N.m/s) are equivalent units of power. Watt (W) is defined as 1 Joule per second. Newton/metre (N/m) is a unit typically associated with force per unit length or surface tension.
