It looks like you're asking: "A year is how much an hour?" - but the question is a bit unclear. I think you might want to know how many hours are in a year, or how to convert a year into hours. Let me clarify both possibilities:

How many hours are in a year?

• 1 year = 365 days (common year)
• 1 day = 24 hours

So:
365 days × 24 hours/day = 8,760 hours in a year For a leap year (366 days):
366 × 24 = 8,784 hours

If you meant something else, like "How much of a year is one hour?"

Then:

• 1 hour ÷ 8,760 hours (in a year) ≈ 0.000114 (about 0.0114%) of a year

If you meant something different, please clarify!
