Light Hours

4.6 Ly^1 × o

640 Ly^1 × o

To clarify the conversion of 640 light-years into different units, we'll break it down into light-hours and light-seconds:

1. Light-Hours

• 1 light-year is the distance light travels in one year.
• 1 year = 8,766 hours.

So, to find out how many light-hours are in 640 light-years:

$\text{Distance in light-hours} = 640 \text{ light-years} \times 8,766 \text{ hours/light-year}$

$\text{Distance in light-hours} = 5,619,840 \text{ hours}$

2. Light-Seconds

• 1 light-year is also the distance light travels in one year.
• 1 year = 31,557,600 seconds.

To find out how many light-seconds are in 640 light-years:

$\text{Distance in light-seconds} = 640 \text{ light-years} \times 31,557,600 \text{ seconds/light-year}$

$\text{Distance in light-seconds} = 20,190,624,000 \text{ seconds}$

Light Hours

• 640 light-years is equivalent to:
  • 5,619,840 light-hours
  • 20,190,624,000 light-seconds
