16:00 EST to GMT
21:00 GMT
16:00 Eastern Standard Time equals 21:00 Greenwich Mean Time.
These are standard-time offsets, which never change. What changes is which one a place observes: New York is on EST in winter but EDT (an hour later) during daylight saving, and the UK is on GMT in winter and BST in summer. If you mean "the time in New York right now", use the full converter — it reads live offsets.
How the conversion works
This one is a formula rather than a single multiplier:
GMT = EST + 5 hours → 21:00 GMT
Going the other way: 21:00 GMT to EST.
