Frequently asked questions
What does the Cartesian to Polar calculate?
Cartesian to Polar Calculator Convert Cartesian coordinates (x, y) to polar coordinates (r, θ) and vice versa. — free online calculator.
Which values should I enter?
Enter Convert, x, y using the units and format shown beside each field.
What formula does this calculator use?
The calculator uses the following relationship: Cartesian → polar: r = √(x²+y²), θ = atan2(y,x); polar → Cartesian: x=r cosθ, y=r sinθ (θ in degrees)..
Why might my result differ from another source?
Results can differ when another source uses different units, rounding rules, conventions or assumptions. Compare the inputs and definitions before comparing results.
Does the result update automatically?
Yes. Changing an input updates the result using the same calculation engine shown on this page.
