How much do you make an hour if you make $49,500 a year?

Could you please explain to me how one might determine their hourly wage if they earn an annual salary of $49,500? I'm trying to understand the calculation process, especially since the number of work hours in a year can vary based on factors like paid time off and holidays. Is there a standard formula or approach that's commonly used to make this calculation? Additionally, how does the number of hours worked per week factor into this equation? I'm curious to know the steps involved in converting an annual salary into an hourly rate.
