RobotC Motor

Hi, I am recently confused about RobotC. In RobotC, for its function motor] = some number, what is the unit of the number? Is it in feet/s?

The number represents a power value. In VEX, the top power value is 127, so 50 would be 50 out of 127 power. It is kinda confusing as to 127 versus 100 in lego mindstorms but thats the way it is.

Thanks. Is that mean if I set motor] = 100 for a motor, the motor will run at speed of 100/127 of its maximum speed?

essentially this is the concept, good luck
