No, there is no standard Newton in a cabinet somewhere. The Newton is defined using the standards for the meter, kilogram and second.
Newton
The Newton is the standard (SI) unit of force, if that's what you mean.
The Newton, N is the standard unit for force.

newton
The standard force is measured in newton. The newton, symbol: N, is the SI derived unit of force, named after Isaac Newton in recognition of his work on classical mechanics. The newton is the unit of force derived in the SI system; it is equal to the amount of force required to give a mass of one kilogram an acceleration of one meter per second squared.

The SI unit of force is the "newton". Weight is a force.
The metric unit for weight (or for any other force) is the "Newton". 1 pound = about 4.4484 newtons. 1 newton = about 3.6 ounces.
Kilogram is a measure of weight. The newton is a measure Weight and motion, which results in force.
Weight is a force. The standard metric unit of force is the Newton, defined as one kilogram-meter per second squared.
