Why people convert Chile to KST time

Scheduling a call from Chile to KST: a 10:00 AM start in Chile lands at 10:00 PM in KST, so you can confirm the slot without doing the arithmetic yourself.
Handling a +12h gap: Chile and KST 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 KST is 9:00 PM in Chile.
Keeping family and friends in sync: knowing that 8:00 PM in Chile is 8:00 AM in KST makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM CLST" is unambiguous; "3 PM" across a +12h gap is not.
With a +12h gap there is no shared 9-to-5 window, so alternate the early start: one week Chile takes the early slot, the next week KST does.
