# How to Convert Spherical to Cartesian | Coordinate Units

Last Updated on March 19, 2023

The image below represents spherical to cartesian.

To convert spherical to cartesian, three essential parameters are needed and these parameters are the Value of r, the Value of θ, and the Value of φ.

The formula for converting spherical to cartesian (x, y, z):

x = rsinθcosφ

y = rsinθsinφ

z = rcosθ

Let’s solve an example;
Find the conversion of spherical to cartesian when the value of r is 2, the value of θ is 8 and the value of φ is 4.

This implies that;

Value of r = 2
Value of θ = 8
Value of φ = 4

Finding x:

x = 2 x sin(8°) x cos(4°)
x = 2 x 0.139 x 0.997
x = 0.277

Therefore, is 0.277.

Finding y:

y = 2 x sin(8°) x sin(4°)
y = 2 x 0.139 x 0.069
y = 0.019

Therefore, is 0.0019.

Finding z:

z = 2 x cos(8°)
z = 2 x 0.9902680687415704
z = 1.98

Therefore, z is 1.98.

Therefore, the Cartesian coordinates of the spherical coordinates (2, 8°, 4°) is (0.27, 0.019, 1.98).
