Implication

Precision metrology study reports an updated quantized Hall resistance in electrical standards, indicating closer alignment with the SI ohm.

Key Points

Determine a refined value for the quantized Hall resistance in terms of the SI ohm as realized by the National Measurement Laboratory calculable cross capacitor.
Realized the SI ohm using the National Measurement Laboratory (Australia) calculable cross capacitor standard.
Reassessed experimental corrections and systematic uncertainties across measurement protocols relative to the prior 1988 evaluation.
The updated 1995 determination produced a quantized Hall resistance value of RK = [1 + 0.4(4.4) × 10^-8] RK-90.
The new value shifts closer to the conventional reference standard RK-90 compared to the 1988 value of RK = [1 + 9.2(6.6) × 10^-8] RK-90 and achieves lower uncertainty.
