Good equation for calculating RPM of a wheel?

[Uncommon]

Hello,

I am a programmer and I would need an equation to determine the RPM of a wheel.

1. First I select a point in the wheel.
2. Then I measure the time it takes for the wheel to spin arround once.
3. This would give me the results.

What would be a good equation for this?

Just divide that into 60.

Do you know what "RPM" stands for? It basically tells you the equation.
