I think it would be cool to see the wind speed displayed over the anemometer. And also using Minecraft units instead of real world units. Units could be toggled by right clicking on the anemometer.

My idea for available units:

• Blocks per second = 1 meter per second = 3.28 feet per second

• Chunks per minute = 1.6 decameters per minute = 17.5 yards per minute.

• Megachunks (100 chunks) per hour = 1.6 kilometers per hour = 1 mile per hour

Nope, I think it will be used like this: 2.0, 0.01, etc. 2.0 means high wind, 0.01 means calm wind.
