The earth's rotational speed is one revolution per day. It doesn't matter where on earth you stand, that is the rotational velocity. I believe that you mean to ask the TANGENTIAL velocity of any point on the earth due to the earth's rotation. To compute this approximately, you need to know two
things: the latitude of the point on the earth's surface, and the circumference of the earth.
The circumference of the Earth at the equator is 25,000 miles. The Earth rotates in about 24 hours. Therefore, if you were to hang above the surface of the Earth at the equator without moving, you would see 25,000 miles pass by in 24 hours, at a speed of 25000/24 or just over 1000 miles per hour.
Multiply by cosine of your latitude to see how fast the Earth is rotating where you are.

According to Wikipedia, the rotation velocity at the equator is 465.11 meters per second.
The link below has a lot of good information about the earth. Browse the orbital and physical characteristics in the sidebar on the right.

1 RPD (revolution per day)
15 degrees per hour
At the equator, since the earth is about 24000 miles around, the speed at the surface is 1000 mph.

Depends on where you happen to be standing.
Diameter at equator is (say) 24000 mile. So at that point you travel at 1000 miles an hour.
Stand at the north/south pole pole and you don't move at all. Unless it equinox when you are moving.
An airplane going west to east at the equator at 1000 mph isn't actually moving at all. Go figure.

24 hours per round.

24 hours.

1,000 miles an hour so that guy who answered before me is right!
