Why people convert São Paulo to Perth time

Scheduling a call from São Paulo to Perth: a 10:00 AM start in São Paulo lands at 9:00 PM in Perth, so you can confirm the slot without doing the arithmetic yourself.
Handling a +11h gap: São Paulo and Perth 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 Perth is 8:00 PM in São Paulo.
Booking travel or deliveries: tracking Perth local time against São Paulo keeps pickup windows and arrival estimates honest across the +11h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM BRT" is unambiguous; "3 PM" across a +11h gap is not.
With a +11h gap there is no shared 9-to-5 window, so alternate the early start: one week São Paulo takes the early slot, the next week Perth does.
