How 1 month converts to hours
Every time conversion goes through the second, which is the SI base unit for time. 1 month is 2,629,746 seconds, and dividing that by the length of one hour gives the answer.
1 month = 730.5 hours 1 × 730.5 = 730.5
Written as a clock reading rather than a decimal, that is 30 days 10 hours 29 minutes 6 seconds. The decimal form is what a form field or a spreadsheet wants; the clock form is what a schedule wants, and the two are not interchangeable.
Where 1 month shows up
Seven hundred thirty and a half hours, and the rounded 730 is a real billing convention: cloud providers including AWS price a monthly rate as 730 hours, which is 8,760 divided by 12. The alternative, 720 hours for a 30-day month, undercounts every 31-day month by a full day. Neither figure equals the month you are actually in, which runs 672, 696, 720 or 744 hours, and that is rather the point of using an average.

Frequently asked questions
How many hours is 1 month?
1 month = 730.5 hours. 1 month = 730.5 hours, so the conversion is 1 × 730.5 = 730.5. Because the calculation involves a month or a year, it uses the Gregorian average rather than a real calendar span, so treat it as an estimate.
How long is 1 month on a clock?
30 days 10 hours 29 minutes 6 seconds. That is the same span written out in whole units instead of a decimal, which is usually what you want when you are setting a timer or reading a schedule rather than filling in a form.
Why is this an estimate rather than an exact answer?
Months are 28 to 31 days and years are 365 or 366, so neither has a single fixed length. This page uses the Gregorian average — 365.2425 days a year, which is a twelfth of that, or 30.436875 days, a month. For a span between two real calendar dates, use the date difference calculator instead; it counts the actual days.
