A simple formula is derived for the Ricci scalar curvature of any smooth level set ψ(x0,x1,...,xn)=C embedded in the Euclidean space \mathbb Rn+1, in terms of the gradient ∇ψ and the Laplacian Δψ. Some applications are given to the geometry of low-dimensional p-harmonic functions and high-dimensional harmonic functions.
