lightyear expressed in units of meters? The speed of light is 3.00 × 108 m/s.

**DrBob222**, Wednesday, January 18, 2012 at 3:47pmThe speed is 3.00E8 m/s so it will travel in 1 year how far?

There are 60 seconds in minute.

There are 60 minutes in 1 hour.

There are 24 hours in a day.

There are 365 days in a year.

Put all of that together. You know the factor is set up correctly if the unit you don't want to keep cancels and leaves the unit you want to keep. The first factor is

60 sec/min.

3.00E8 m/s x (60 sec/min). Note the sec cancel and leaves you with 3.00E8m/min. The next factor will convert to hours, the next to days, the next to years.
