A corrected calculation puts the San Diego-to-Pearl Harbor distance at roughly 3,022 nautical miles. At a sustained 30 knots the voyage is about 4.2 days, although maintaining that speed for the whole passage is rarely realistic. At 18 knots the trip is roughly seven days, while at 10 knots it becomes about 12.6 days. The comparison shows why nominal top speed, economical cruising speed, and convoy pace produce very different strategic timelines.

How speed changes the voyage to Pearl Harbor
A checked calculation turns one Pacific distance into very different reinforcement times at 30, 18, and 10 knots.
