The Polar to Rectangular Calculator is a powerful tool that converts polar coordinates (r, θ) to rectangular coordinates (x, y). This conversion is essential in various fields, including mathematics, physics, engineering, and navigation. Our calculator simplifies this process by providing instant, accurate conversions along with visual representations.
Understanding the relationship between polar and rectangular coordinates is crucial for many applications. Polar coordinates describe a point's location using a distance from the origin (r) and an angle from the positive x-axis (θ), while rectangular coordinates use perpendicular distances (x, y) from the origin. This calculator helps bridge these two coordinate systems, making it easier to work with both representations.
Think of rectangular coordinates like giving directions on a city grid:
Polar coordinates are like giving directions using a distance and angle, similar to a radar or compass:

The conversion from polar to rectangular coordinates uses two fundamental trigonometric formulas:
x = r × cos(θ)
Where r is the radius and θ is the angle in radians
y = r × sin(θ)
Where r is the radius and θ is the angle in radians
Let's convert a point from polar to rectangular coordinates using our calculator. We'll use a common example that demonstrates the conversion process clearly.
Convert the polar coordinates (5, 45°) to rectangular coordinates:
θ (in radians) = 45° × (π/180°)
= π/4 radians
x = r × cos(θ)
x = 5 × cos(π/4) ≈ 3.5355
y = r × sin(θ)
y = 5 × sin(π/4) ≈ 3.5355
The polar coordinates (5, 45°) convert to rectangular coordinates (3.5355, 3.5355). This point lies on a circle with radius 5, at an angle of 45° from the positive x-axis.

Q1. What are polar coordinates?
•
Polar coordinates are a way to describe a point's location using two values: the distance from the origin (r) and an angle from the positive x-axis (θ). This system is particularly useful for describing circular or spiral patterns.
Q2. How do you convert from polar to rectangular coordinates?
•
To convert from polar coordinates (r, θ) to rectangular coordinates (x, y), use these formulas: x = r × cos(θ) and y = r × sin(θ). Our calculator handles these calculations automatically.
Q3. What is the formula for converting polar to rectangular coordinates?
•
The formula for converting polar to rectangular coordinates is x = r × cos(θ) and y = r × sin(θ).
Q4. Why would I need to convert polar to rectangular coordinates?
•
Converting between coordinate systems is useful in many fields, including physics (describing circular motion), engineering (antenna patterns), navigation (radar systems), and mathematics (complex number operations).
Q5. What angle units does the calculator use?
•
The calculator accepts angles in degrees for user convenience. It automatically converts these to radians for the calculations, as trigonometric functions in mathematics typically use radians.
Q6. How accurate are the calculated results?
•
Our calculator provides results to four decimal places, which is sufficient for most practical applications. The calculations use standard mathematical libraries for maximum precision.
Q7. Is Polar to Rectangular Calculator free?
•
Yes, Polar to Rectangular Calculator is free to use.
Q8. Can I use negative values for radius or angle?
•
While the calculator accepts negative angles, it's generally preferred to use a positive radius with an appropriate angle. A negative radius with an angle is equivalent to a positive radius with the angle rotated by 180°.
Q9. What does the visualization show?
•
The visualization shows your point plotted on a Cartesian (rectangular) coordinate system, along with a circle indicating the radius. This helps you understand the relationship between polar and rectangular representations.
Q10. Where are polar coordinates commonly used?
•
Polar coordinates are commonly used in navigation (radar systems), physics (circular motion), engineering (antenna radiation patterns), and mathematics (complex number analysis and calculus).
Q11. Are there any shortcuts to convert polar to rectangular coordinates?
•
Yes, there are some shortcuts to convert polar to rectangular coordinates. For example, if the angle is 0°, the x-coordinate is r and the y-coordinate is 0. If the angle is 90°, the x-coordinate is 0 and the y-coordinate is r. If the angle is 180°, the x-coordinate is -r and the y-coordinate is 0. If the angle is 270°, the x-coordinate is 0 and the y-coordinate is -r.
Q12. What is the difference between polar and rectangular coordinates?
•
The main difference between polar and rectangular coordinates is that polar coordinates use distance (r) and angle (θ) to specify a point's location, while rectangular coordinates use horizontal (x) and vertical (y) distances.
