Golf course putting green speed is measured with a device called a "Stimpmeter". The Stimpmeter is basically an aluminum channel on which a golf ball rests. When one end is raised to a specific height, the ball travels down the channel and travels a certain distance on the green. That distance is measured in feet and is then considered the speed of the green. So a green with a speed of 10 means that the ball traveled 10 feet from the Stimpmeter.

The original intention of the Stimpmeter was to ensure that all the greens on a course were of relatively equal speed. This would provide the Superintendent with a method to evaluate the speed of different greens and then take the appropriate action to make them equal.
