A light-year is a unit of distance, not time. It represents the distance that light travels in one year in a vacuum, which is approximately 9.461 trillion kilometers or about 5.88 trillion miles.
However, if you're asking about the concept of "human years" in relation to a light-year, it's important to note that the two are not directly comparable. A human year is a measure of time, representing the time it takes for the Earth to complete one orbit around the Sun, which is about 365.25 days.
Since a light-year measures distance and a human year measures time, they are fundamentally different units and cannot be converted into one another. It's like trying to compare miles to hours or kilograms to seconds—they represent different aspects of measurement.
So, to summarize, a light-year is a unit of distance, while a human year is a unit of time, and they do not have a direct conversion between them.
