What do you mean by one newton force

A newton (N) is the international unit of measure for force. One newton is equal to 1 kilogram meter per second squared. In plain English, 1 newton of force is the force required to accelerate an object with a mass of 1 kilogram 1 meter per second per second.

I mean the force that would accelerate 1 kilogram of mass at the rate of 1 m/s per second.

It's roughly the same as 3.6 ounces of force.
