Cartesian Cylindrical and Spherical Coordinates

How to use Cartesian Cylindrical and Spherical Coordinates

Cartesian points use hypot and atan2 for stable radii and azimuth. Spherical inclination is measured from+z, not elevation above the xy plane. Inverse modes use your radius/angles; zero/pole azimuth remains explicitly not defined.

1. Enter x or radius, y or azimuth degrees, z or polar inclination degrees.
2. Choose the stated convention and check the units and supported model.
3. Calculate, inspect the result, then copy or download it.

Good to know

• Matching arbitrary length units, degree angles. Inverse radius nonnegative, azimuth−360..360 and inclination0..180. No latitude/longitude, map projection, theoretical key spelling or separate2D-only polar page.
• Runs locally. Text/JSON fields are capped at30,000 characters; stricter page-specific and numeric-string limits also apply. Numeric inputs are bounded to magnitude1e15 and nonzero magnitude at least1e-100 unless an exact-string mode states otherwise. Approximate summaries use12 significant digits; CSV numeric cells retain the complete stored value and potentially formula-like string cells gain a protective apostrophe; unsupported, non-finite or detected underflow states return an error.
