Cartesian and Polar Coordinates: Cartesian To Polar Coordinates Calculator
Coordinate systems are mathematical frameworks used to locate points in space or on a plane. Two commonly used coordinate systems are Cartesian coordinates and polar coordinates.
Cartesian Coordinates
Cartesian coordinates, also known as rectangular coordinates, use a grid system with two perpendicular axes, x-axis and y-axis. The point of intersection of these axes is called the origin. Each point in the Cartesian plane is identified by an ordered pair of numbers (x, y), where x represents the horizontal distance from the origin along the x-axis, and y represents the vertical distance from the origin along the y-axis.
Polar Coordinates
Polar coordinates, also known as cylindrical coordinates, use a different approach to locate points. They use a radial distance r and an angle θ. The radial distance r is the distance from the origin to the point, and the angle θ is the angle between the positive x-axis and the line connecting the origin to the point.
The relationship between Cartesian and polar coordinates is given by the following equations:
x = r cos(θ)y = r sin(θ)
Conversion Formulas
Converting from Cartesian coordinates to polar coordinates involves applying specific mathematical formulas. These formulas allow us to represent a point in the Cartesian plane using its distance from the origin and its angle relative to the positive x-axis.

- Radius (r): r = √(x² + y²)
- Angle (θ): θ = arctan(y/x)
Examples of Cartesian to Polar Conversions
Let’s convert the point (3, 4) from Cartesian to polar form:
- r = √(3² + 4²) = 5
- θ = arctan(4/3) ≈ 0.9273 radians
Therefore, the polar coordinates of the point (3, 4) are (5, 0.9273).

Calculator Functionality
Cartesian to polar coordinates calculators are mathematical tools that facilitate the conversion of points between the Cartesian coordinate system (x, y) and the polar coordinate system (r, θ).
Using a Cartesian to polar coordinates calculator is straightforward. Simply input the x and y coordinates of the point you want to convert into the designated fields. The calculator will automatically calculate and display the corresponding polar coordinates (r, θ).
Conversion Scenarios
- Converting a point in the Cartesian coordinate system to polar coordinates:For example, to convert the point (3, 4) in the Cartesian coordinate system to polar coordinates, input the values x = 3 and y = 4 into the calculator. The calculator will return the polar coordinates (r, θ) = (5, 53.13°).
- Converting a point in the polar coordinate system to Cartesian coordinates:For example, to convert the point (5, 53.13°) in the polar coordinate system to Cartesian coordinates, input the values r = 5 and θ = 53.13° into the calculator. The calculator will return the Cartesian coordinates (x, y) = (3, 4).
Applications and Examples
Converting between Cartesian and polar coordinates finds practical applications in various fields. It allows for convenient representation, analysis, and problem-solving in situations where circular or angular relationships are involved.
The following are examples of real-world applications where converting between Cartesian and polar coordinates is useful:
