This page will calculate how fast a theoretical space habitat of given diameter would need to spin to achieve 1G of centripetal acceleration, efffectively simulating Earth gravity.

By specifying body speed you can also get value of Coriolis acceleration acting on the body.
Earth diameter is 6300000 meters, hence on a body moving at 100 km/h, Coriolis acceleration is 1% of 1 g.
