  The Standard Model can be defined quantitatively by running parameters in a
mass-independent renormalization scheme at a fixed reference scale. We provide
a set of simple interpolation formulas that give the fundamental Lagrangian
parameters in the $\bar{\rm MS}$ scheme at a renormalization scale of 200 GeV,
safely above the top-quark mass and suitable for matching to candidate new
physics models at very high mass scales using renormalization group equations.
These interpolation formulas take as inputs the on-shell experimental
quantities, and use the best available calculations in the pure $\bar{\rm MS}$
scheme. They also serve as an accounting of the parametric uncertainties for
the short-distance Standard Model Lagrangian. We also include an interpolating
formula for the W boson mass.
