Leveraging the revised International System of Units: torque from the fundamental constants Open
Calibration of tools designed to apply known torques, such as torque wrenches and torque screwdrivers, requires a chain of traceable standards to the definition of the kilogram and meter derived from the revised International System of Uni…

Thoughts on the Kibble–Robinson theory Open
We revisit the Kibble–Robinson theory, first proposed in 2014 by Kibble and Robinson. This theory significantly simplifies the construction and operation of Kibble balances. We conducted a theoretical investigation of the theory’s assumpti…

The Design and Performance of an Electronic Torque Standard Directly Traceable to the Revised SI Open
The United States National Institute of Standards and Technology (NIST) has been developing a new device for primary standard realization of torque utilizing established traceability to quantum-electrical standards following the 2019 revis…
