Abstract

We measure a cryogenic, vacuum-gap capacitor by two methods: 1) charging it with a known number of electrons and measuring the resulting voltage, and 2) using a capacitance bridge traceable to the SI farad. We report a detailed uncertainty budget for the comparison of the two methods and find that they agree within a relative standard uncertainty of $9.2 \times 10^-7}$. This comparison closes the quantum metrology triangle with the same uncertainty.
