In physics and mathematics, a pseudotensor is usually a quantity that transforms like a tensor under an orientation preserving coordinate transformation (e.g., a proper rotation), but gains an additional sign flip under an orientation reversing coordinate transformation (e.g., an improper rotation, which is a transformation that can be expressed as an inversion followed by a proper rotation).
