ratio question: 216.1:1 - how many rotations per minute is that?
I'm thinking of buying a Worm Gear motor/Box 216.1:1 and 336.1:1...
Only problem is, I don't know how many rotations per minute/second that is.

Gears have rotations only when turning.
Your gearbox has a gear ratio of 216.1:1. That means for every 216 turns on the input, the output turns once.
Take the rotation rate of the input (the motor driving the gearbox) and divide by 216 to get rotation rate of output.
