An hour is a unit of time, and a year is a much larger unit of time typically defined as the period it takes the Earth to complete one orbit around the Sun.

In a standard year (365 days), there are 8,760 hours. This is calculated by multiplying 365 days by 24 hours per day:
365×24=8,760365\times 24=8,760365×24=8,760 hours. -
In a leap year (366 days), there are 8,784 hours:
366×24=8,784366\times 24=8,784366×24=8,784 hours. -
The mean year, which averages the length of a year over long periods including leap years, is approximately 365.25 days, which equals about 8,766 hours:
365.25×24=8,766365.25\times 24=8,766365.25×24=8,766 hours.
Thus, one hour is 1/8,760 (or roughly 1/8,766) of a year depending on the year type considered. So, when you ask "an hour is how much a year," it means that an hour is a very small fraction of a year, approximately 0.000114 of a standard year (1 hour ÷ 8,760 hours).
