We review measurements of star formation rates (SFRs) at multiple wavelengths, comparing indicators commonly used in Milky Way studies with those used for external galaxies, and highlighting similarities and differences. Choices of the most appropriate SFR indicators for investigations in the two environments (Milky Way versus external galaxies) are driven by basic observational differences between the two, such as the dust column density (substantially larger towards the Galactic Center than towards a typical external, unresolved or partially resolved, galaxy) and the spatial resolution. Recent progress in the calibration of mid--infrared SFR indicators enabled by the Spitzer Space Telescope is reviewed with an outlook on the expected capabilities of future missions. SFR calibrations collected from the literature, from the X--ray to the radio, are presented after re--normalization to a common Kroupa stellar initial mass function.
