Why people convert United Kingdom to NST time

Scheduling a call from United Kingdom to NST: a 10:00 AM start in United Kingdom lands at 5:30 AM in NST, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both United Kingdom and NST are inside the 9-to-5 working day between 1:30 PM and 5:00 PM BST time (9:00 AM–12:30 PM NST). That is roughly 3 hours 30 minutes of usable overlap.
Watching a live event or market open: United Kingdom viewers need 4:30 AM in NST to catch a 9:00 AM start there, and 4:30 AM if the event is anchored to United Kingdom.

Always state the zone abbreviation, not just the hour. "3:00 PM BST" is unambiguous; "3 PM" across a -4h 30m gap is not.
Block 1:30 PM–5:00 PM BST as the recurring meeting window if you work primarily from United Kingdom and need NST colleagues present.

About GMT (Greenwich Mean Time)

Greenwich Mean Time (GMT) is the clock time at the Royal Observatory in Greenwich, London, which sits on the Prime Meridian (0° longitude). GMT serves as the reference point from which all other time zones are calculated. The United Kingdom uses GMT during winter months and switches to British Summer Time (BST, UTC+01:00) from late March to late October. Several West African nations use GMT year-round. GMT is often used interchangeably with UTC (Coordinated Universal Time), although technically they are different – UTC is based on atomic clocks while GMT is based on Earth's rotation.

About NST (Newfoundland Standard Time)

Newfoundland Standard Time (NST) is one of the few half-hour offset time zones in the world. It covers the island of Newfoundland in Canada and is 30 minutes ahead of Atlantic Standard Time. This unique offset exists because Newfoundland was an independent country until 1949.
