Dictionary entry
This is a dictionary definition. It should not be an encyclopedia article. It can be defined along with related units of measure in the speed of light article. -Eric talk 12:06, 21 June 2008 (UTC)
The light-year article is the appropriate place to describe the concept of expressing distance in terms of how far light travels in a given time interval, that term being the most widely known one for this approach to distance measurement. Substituting 'year' with other units of time measurement and making a stub on each one is unnecessary clutter. A simple list at the end of the light-year article will suffice. -Eric talk 12:26, 25 June 2008 (UTC)
- I've merged most of the shorter "light-time" units in here, because the light-second is the one which is actually used in several scientific contexts. Physchim62 (talk) 11:14, 10 May 2009 (UTC)

nanosecond as a distance
Here's a wierd coincidence,
1 nsec = 300 mm
1 English ft = 305 mm
1 Roman ft = 296 mm
Conclusion: The Roman foot was closer to the nanosecond than the modern English foot for whatever it's worth.

Mars - Earth distance in light-minutes = 4 - 24 minutes.
Light-minute distance from the Earth to the Mars is between around 4 minutes to 24 minutes.
