How to Convert Cartesian to Spherical | Coordinate Units

Three essential parameters are needed to convert cartesian to spherical: the value of x, the value of y, and the value of z.

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

r = √(x² + y² + z²)

φ = tan-1(y / x)

θ = tan-1((√(x² + y²) / z)

Let’s solve an example;
Find the conversion of cartesian to spherical when the value of x is 4, the value of y is 3 and the value of z is 6.

This implies that;

Value of x = 4
Value of y = 3
And, Value of z = 6

Finding r:

r = √(4² + 3² + 6²)
r = √(16 + 9 + 36)
So, r = √(61)
r = 7.81

Therefore, r is 7.81

Finding θ:

θ = tan-1((√(4² + 3²)) / 6)
That is, θ = tan-1((√(16 + 9)) / 6)
θ = tan-1((√(25)) / 6)
θ = tan-1((5) / 6)
So, θ = tan-1(0.8333333333333334)
θ = 39.80°

Therefore, θ is 39.80°.

Finding φ:

φ = tan-1(3 / 4)
That is, φ = tan-1(0.75)
φ = 36.86°
