Convert light speed (vacuum) to furlong/fortnight
Selected category: speed.
Definition and details for light speed (vacuum):
Speed of light (c) in vacuum is equal to 299 792 458 meters/sec with a relative measurement uncertainty of 4 parts per billion. Up to 17th century humanity wasn't sure if light was transmitted instantaneously or simply very quickly. The Danish astronomer, Ole Christensen Rømer first demonstrated that light travelled at a finite speed when he studied the apparent motion of Jupiter's moon Io.
Definition and details for furlong/fortnight:
Furlong per fortnight is a unit of velocity used to measure speed at sea. Furlong is equal to 201.168 meters and a fortnight is a traditional unit of time equal to 2 weeks. So one furlong per fortnight is 201.168 meters per 2 weeks or about 1.6631x10-4 m/sec.
