How do you calculate km in a light-year?

How do you calculate km in a light-year?

In a vacuum, light travels at 670,616,629 mph (1,079,252,849 km/h). To find the distance of a light-year, you multiply this speed by the number of hours in a year (8,766). The result: One light-year equals 5,878,625,370,000 miles (9.5 trillion km).

How far away is 1 light-year in km?

Light-year is the distance light travels in one year. Light zips through interstellar space at 186,000 miles (300,000 kilometers) per second and 5.88 trillion miles (9.46 trillion kilometers) per year.

How do you convert ly to KM formula?

How do I convert light year into km? One light year is 9.5 million million km, so multiply the number of light years by 9.5 million million (or 9.5 trillion).

How do you convert years to light-years?

1. A light year is a distance.
2. It is the distance light travels in one year.
3. As light travels at constant speed, the distance light travels in a year can be calculated using the equation:
4. Distance = speed x time.
5. time = 1 year = 365 x 24 x 60 x 60 = 31,536,000 s.

Why is it calculated in light years?

A light-year is a measurement of distance in space. The astronomical distances are measured in light-years because, the speed of light is constant throughout the universe and is known to high precision.

How long is 1km light?

0.0000033 seconds to travel 1 kilometer; 1.3 seconds to reach us from the Moon; 8.32 minutes to reach us from the Sun; 4.37 years to reach us from Alpha Centauri, the nearest star system to the Solar System (Alpha Centauri is therefore said to be 4.37 light years away);

How long is 1 light-year in Earth years?

Since light travels at about 186,300 miles per second, with 86,400 seconds per day and about 365 days per year, that works out at about: 186300×86400×365≈5,875,000,000,000 miles.

What is light-year class 12?

One light year is defined as the the distance travelled by light in one year in vacuum.

How do you convert km to time?

1. convert kilometres per hour to kilometres per minute (70km/h / 60 minutes = 1.17km/min), therefore 1.7km/min * 255 minutes = 297.5km.
2. or convert 255 minutes to a decimal hour by doing 255 minutes / 60 minutes = 4.25 hours, which gives us the figure we had before.

How do you calculate travel time in km?

Time = distance/speed. So, a nice easy one would be how many hours does it take to cover 30km when you are travelling at 120km/h. Time = 30km/120km/h = 0.25 hours. If you need to figure out how many minutes that is, simply multiply it by 60, which gives you 15 minutes.

How do you convert light speed to kilometers?

1. 1 m = 11000km.
2. 1 sec = 13600h.
3. Speed of light = 299792458×36001000 km/h.
4. Speed of light = 1.079×109 km/h.
