  Coaxial 2-terminal bridge comparison is a widely used metrological method in
the dissemination of value of capacitance up to 1000 pF and $10^4$ rad/s. In
this range, capacitance can be measured with uncertainties as small as few
parts in $10^{7}$; however, such measuments must take into account the
corrections due to the impedance of cables, connectors and ports, which can
tipically amount up to $10^{-8}$ $\mu$F/F $-$ and maybe larger. In this work,
we report on how correction factors in 2-terminal pair coaxial bridge
capacitance measurements are presently measured and calculated at Inmetro.
