# How to Convert Cylindrical to Spherical | Coordinate Units

Last Updated on June 19, 2024

To convert cylindrical to spherical, three essential parameters are needed: the Value of ρ, the Value of φ, and the Value of z.

### The formula for converting cylindrical to spherical (r, θ, φ):

r = √(φ² + z²)

θ = tan-1(ρ / z)

φ = φ

Let’s solve an example;
Find the conversion of cylindrical to cartesian when the value of ρ is 2, the value of φ is 3 and the value of z is 5.

This implies that;

Value of ρ = 2
Value of φ = 3
And, Value of z = 5

Finding r:

r = √(2² + 5²)
r = √(4 + 25)
That is, r = √(29)
r = 5.38

Therefore, is 5.38

Finding θ:

θ = tan-1(2 / 5)
θ = tan-1(0.4)
So, θ = 21.80°

Therefore, θ is 21.80°.

Finding φ:

φ = 3°

Therefore, the spherical coordinates of the cylindrical coordinates (2, 3°, 5) is (5.38, 21.80°, 3°).
