So, I'm wrong. GEEEZ! I hate being wrong when arguing with Imaginarians.
How many mph does it take to obtain 1G? How much time and speed would it take earthlings at our present technology to visit a planet orbiting Centauri?

Gravity is change in velocity, not velocity itself. You can express it in Miles Per Hour
Per Second. IIRC, 1G is equal to approximately 20 mph/sec. Meaning, every second you add 20 mph to your velocity. Deceleration is the same as acceleration to a physicist, you are merely accelerating in a different direction. The same is true for any change in direction, even making a turn. It's all acceleration because the same math applies.
The fastest way to get from point A to point B in space is to use a thruster you can operate constantly and accelerate towards your target for halfway, then accelerate in the opposite direction for the rest of the trip.
