The order of magnitude pages is really an excellent idea -- Egil

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)[reply]

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)[reply]

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)[reply]

Good idea. Eric ^talk 14:40, 24 May 2009 (UTC)[reply]

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.
