What Does C Represent in Physics Equation t = C X sqrt(h/g)?

[Abder-Rahman]

I was looking at a Physics class from the MIT. The Professor gave this equation to the "Time":

t = C X sqrt(h/g)

What does or can the "C" which is I think is a "Constant" here represent?

Thanks.

This looks to me to be the equation for the period of a pendulum of length H, where C is 2*pi.

Thank you for your reply.

What I have here is that he said that:

C = sqrt(2)

Does that make sense?

Thanks.
