Why people convert Delhi to HKT time

Scheduling a call from Delhi to HKT: a 10:00 AM start in Delhi lands at 12:30 PM in HKT, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Delhi and HKT are inside the 9-to-5 working day between 9:00 AM and 2:30 PM IST time (11:30 AM–5:00 PM HKT). That is roughly 5 hours 30 minutes of usable overlap.
Watching a live event or market open: Delhi viewers need 11:30 AM in HKT to catch a 9:00 AM start there, and 9:30 PM if the event is anchored to Delhi.

Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +2h 30m gap is not.
Block 9:00 AM–2:30 PM IST as the recurring meeting window if you work primarily from Delhi and need HKT colleagues present.

About IST (India Standard Time)

India Standard Time (IST) is the time observed throughout India and Sri Lanka. It is based on the 82.5°E meridian, passing through Mirzapur in Uttar Pradesh. India uses a single time zone despite spanning roughly 30° of longitude, which has been debated. IST does not observe daylight saving time. India is the world's most populous country, making IST one of the most-used time zones globally. The IT outsourcing industry and call centers operate primarily on IST, making the EST-to-IST conversion one of the most searched timezone conversions.

About HKT (Hong Kong Time)

Hong Kong Time (HKT) is fixed at UTC+08:00 all year and does not observe daylight saving time. Hong Kong last used summer time in 1979 and has kept a single offset since. HKT shares the UTC+08:00 offset with China Standard Time, Singapore Time, Malaysian Time, Philippine Time and Australian Western Standard Time, but is listed separately because Hong Kong maintains its own timekeeping authority. As a major financial centre, Hong Kong's trading hours set the rhythm for markets across Asia, opening at 09:30 HKT which is 01:30 in London and 20:30 the previous evening in New York.
