WebFormula of the Radius of Curvature Normally the formula of curvature is as: R = 1 / K’ Here K is the curvature. Also, at a given point R is the radius of the osculating circle (An imaginary circle that we draw to know the radius of curvature). Besides, we can sometimes use symbol ρ (rho) in place of R for the denotation of a radius of curvature.
