How to convert energy in (Nm or Joule) into power in (watt) ?My posted question is related with unit conversion

Newton is a unit of force. The force applied over a
particular distance gives energy. This can be expressed either as Newton meter or in the
SI unit which for energy is joule. Watt is the SI unit for power. Power is energy per
unit time or Joule/second. It is not possible to convert energy to power
directly.

You can calculate power if you know the duration
of time over which the energy was converted. For example, if 10 joule of energy is used
to heat a room in 5 seconds, the power consumption is 2
watt.

You cannot directly convert Nm or J to W as they are
not equivalent units.
