Abstract
The establishment of standards for small force measurement requires a link to an absolute measurement of force traceable to the international system of units (SI). To this end, a host of different means are being employed by the NIST small force measurement project to realize and transfer forces between 5 millinewtons and 5 piconewtons. Realizations based on deadweights and electrostatic forces, as well as transfer artifacts based the mechanical properties of single DNA molecules will be discussed. The application of each of these approaches will also be discussed as a calibration method for different kinds of instruments requiring the measurement of small forces.Proceedings Title
