Abstract
We propose a trick for calculating the surface gravity of the Killing horizon, especially for cases of rotating black holes. By choosing nice slices, the surface gravity and angular momentums can be directly read from relevant components of the inverse metric. We give several cases to show how to apply the trick step by step.
