Light Year Conversion
A light year calculator is used to convert between light years and other units of distance, typically kilometers or miles. A light year is the distance light travels in one Earth year, which is approximately 9.46 trillion kilometers or 5.88 trillion miles.
When you want to know how many kilometers are in 2 light years, you would input 2 into the calculator, and it output approximately 18.92 trillion kilometers.Light Year Conversion Chart
| Light Years | Kilometers (trillions) | Miles (trillions) |
|---|---|---|
| 1 | 9.46 | 5.88 |
| 2 | 18.92 | 11.76 |
| 5 | 47.30 | 29.40 |
| 10 | 94.61 | 58.79 |
| 50 | 473.05 | 293.95 |
| 100 | 946.10 | 587.90 |
| 1,000 | 9,461.00 | 5,879.00 |
Light Year Conversion Formula
The formula to convert light years to kilometers is:
Kilometers = Light Years × 9.461 × 10^12For miles, the formula is:
Miles = Light Years × 5.879 × 10^12Let’s use an example to convert 3 light years to kilometers:
3 × 9.461 × 10^12 = 28.383 × 10^12 kilometers or about 28.38 trillion kilometers.How do you Convert Years to Light Years?
To do this, use the following formula:
Light Years = Number of Years × Speed of Light in km/yearThe speed of light is approximately 9.461 × 10^12 km/year.
For example, to calculate how far light travels in 5 years:
5 × 9.461 × 10^12 = 47.305 × 10^12 km or 5 light years.This means that in 5 years, light would travel a distance of 5 light years.
