How long to travel 1 Au at 1G acceleration?

Traveling 1 astronomical unit (AU), which is approximately 93 million miles or 150 million kilometers, at a constant acceleration of 1g (about 9.81 m/s²) would take roughly 2.3 months to reach the destination. This calculation assumes that the spacecraft accelerates at 1g for half the journey and then decelerates at 1g for the second half. The total travel time can vary slightly depending on the specifics of the trajectory and the exact duration of acceleration and deceleration phases.
