We measure the ratio of aluminum and mercury single-ion optical clock frequencies with a fractional uncertainty of \uncertaintyAlHg, comprising a statistical measurement uncertainty of \uncertaintyStat, and systematic uncertainties of \uncertaintyHg and \uncertaintyAl in the mercury and aluminum frequency standards, respectively. This frequency ratio is the best known physical constant that is not a simple integer. Repeated measurements during the past year yield a preliminary constraint on the temporal variation of the fine-structure constant of αdotConstraint.
