Why people convert Bangkok to Perth time

Scheduling a call from Bangkok to Perth: a 10:00 AM start in Bangkok lands at 11:00 AM in Perth, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Bangkok and Perth are inside the 9-to-5 working day between 9:00 AM and 4:00 PM ICT time (10:00 AM–5:00 PM AWST). That is roughly 7 hours of usable overlap.
Keeping family and friends in sync: knowing that 8:00 PM in Bangkok is 9:00 PM in Perth makes it easy to avoid calling at 3 AM.

Always state the zone abbreviation, not just the hour. "3:00 PM ICT" is unambiguous; "3 PM" across a +1h gap is not.
Block 9:00 AM–4:00 PM ICT as the recurring meeting window if you work primarily from Bangkok and need Perth colleagues present.
