formula of Spherical Coordinates to Cartesian Calculator

Here are the formulas for converting spherical coordinates (ρ, θ, φ) to Cartesian coordinates (x, y, z):

x = ρ sin(φ) cos(θ) y = ρ sin(φ) sin(θ) z = ρ cos(φ)


  • ρ (rho) is the radial distance from the origin.
  • θ (theta) is the polar angle, ranging from 0 to 2π.
  • φ (phi) is the azimuthal angle, ranging from 0 to π.

These formulas are fundamental in translating the position of a point from one coordinate system to another, thereby enhancing the understanding of spatial relationships and geometrical properties.
