# How to Convert Polar to Cartesian | Coordinate Units

Last Updated on June 19, 2024

To convert polar to cartesian, three essential parameters are needed: the Value of r and Value of θ.

### The formula for converting polar to cartesian (x, y):

x = rcosθ

y = rsinθ

Let’s solve an example;
Find the conversion of polar to cartesian when the value of r is 4 and value of θ is 8.

This implies that;

Value of r = 4
Value of θ = 8

Finding x:

x = 4 x cos(8°)
That is, x = 4 x 0.99
x = 3.96

Therefore, is 3.96.

Finding y:

y = 4 x sin(8°)
So, y = 4 x 0.139
y = 0.55

Therefore, y is 0.55.

Therefore, the Cartesian coordinates of the polar coordinates (4∠8°) is (3.96, 0.55).
