Cartesian to Polar Coordinates
Convert a point into radius and signed angle using atan2.
Your numbers
Radius
Use consistent units. The result follows the assumptions you enter.
Scenario comparison
Up to three snapshots in this tab. Loading one replaces the current inputs.
Formula
Use r = √(x²+y²) and θ = atan2(y,x). x and y are Cartesian coordinates in the same unit. Radius r keeps that unit; the signed angle θ is converted from radians to degrees for display.

Scope and limitations
Use consistent units. The result follows the assumptions you enter.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
