SrRuO${}_3$ is an itinerant ferromagnet with a Curie temperature of $150\mathrm{K}$ and a uniaxial magnetocrystalline anisotropy. Using high-quality epitaxial thin films, we measure at $2\mathrm{K}$ the anisotropic magnetoresistance and the planar Hall effect as a function of the in-plane current direction and the magnetization orientation. We identify three types of contributions related to (a) the orientation of the magnetization relative to the crystal axes, (b) the direction of the current relative to the crystal axes, and (c) the orientation of the magnetization relative to the current.
