Why people convert Karachi to Honolulu time

Scheduling a call from Karachi to Honolulu: a 10:00 AM start in Karachi lands at 7:00 PM in Honolulu the previous day, so you can confirm the slot without doing the arithmetic yourself.
Handling a -15h gap: Karachi and Honolulu have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Honolulu is 6:00 PM in Karachi.
Watching a live event or market open: Karachi viewers need 6:00 PM in Honolulu to catch a 9:00 AM start there, and 3:00 PM if the event is anchored to Karachi.

Always state the zone abbreviation, not just the hour. "3:00 PM PKT" is unambiguous; "3 PM" across a -15h gap is not.
With a -15h gap there is no shared 9-to-5 window, so alternate the early start: one week Karachi takes the early slot, the next week Honolulu does.
