Why people convert Sri Lanka to IST time

Scheduling a call from Sri Lanka to IST: a 10:00 AM start in Sri Lanka lands at 10:00 AM in IST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Sri Lanka and IST are inside the 9-to-5 working day between 9:00 AM and 5:00 PM IST time (9:00 AM–5:00 PM IST). That is roughly 8 hours of usable overlap.
Booking travel or deliveries: tracking IST local time against Sri Lanka keeps pickup windows and arrival estimates honest across the +0h offset.

Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +0h gap is not.
Block 9:00 AM–5:00 PM IST as the recurring meeting window if you work primarily from Sri Lanka and need IST colleagues present.
