We report on a 2012 comparison of gravity used to determine the Planck constant by the National Institute of Standards and Technology (NIST) and the National Research Council Canada (NRC) watt balances. The results provide verification of the gravity
In a watt balance (WB) the gravity on a known mass is used in the determination of the value of the Planck constant with a precision of

We report on a 2012 absolute gravity comparison performed at the National Institute of Standards and Technology (NIST), Gaithersburg, MD. Unique to this work is the direct comparison of gravitational measurement systems used in the determination of t

In 2009 NRC commenced construction of a new laboratory to house the NRC watt balance. We describe the procedures used and give results for the measurements of the acceleration due to gravity in the new laboratory. The data will be linked both to thos
