A light-year is the distance that light travels in a vacuum in one Julian year (365.25 days). It's a unit of astronomical distance.

50,000 meters is equal to 50 kilometers or about 31 miles.

A light-year is an enormous distance, representing trillions of kilometers. 50,000 meters is a very small distance by comparison, relevant on Earth but minuscule in space.

Direct conversion of such small meter values to light-years is rarely used in practice because the resulting number is incredibly close to zero, making it impractical for astronomical measurements.
