Why is the Prime Meridian in Greenwich?
It was desirable to adopt a single world meridian to replace the numerous one's already in existence.
The Meridian passing through the principal Transit Instrument at the Observatory at Greenwich was to be the 'initial meridian'.
That all longitude would be calculated both east and west from this meridian up to 180°.
All countries would adopt a universal day.
The universal day would be a Mean Solar Day, beginning at the Mean Midnight at Greenwich and counted on a 24 hour clock.
That nautical and astronomical days everywhere would begin at mean midnight.
All technical studies to regulate and extend the application of the decimal system to the division of time and space would be supported.
Resolution 2, fixing the Meridian at Greenwich was passed 22-1 (San Domingo voted against), France
