Re: Creates more problems than it solves?

When the meter was invented and defined, the speed of light was not known.
The metre was invented on 17 March 1791. Ole Roemer estimated the speed of light at 200,000 km/s in 1675 and James Bradley gave the number 301,000 km/s in 1728.

Today of course Merkins know that it's 299792.4574 ± 0.0011 km/sec and the British know that it's 299792.4590 ± 0.0008 km/sec.
