How 1 hour converts to minutes
Every time conversion goes through the second, which is the SI base unit for time. 1 hour is 3,600 seconds, and dividing that by the length of one minute gives the answer.
1 hour = 60 minutes 1 × 60 = 60
Where 1 hour shows up
The hour is not an SI unit. The International Bureau of Weights and Measures lists it among the non-SI units accepted for use with the SI, defined as exactly 60 minutes or 3,600 seconds — a legacy kept because no redefinition was ever going to persuade the world to abandon it. The second underneath it is the rigorous one, fixed by the caesium-133 hyperfine transition at 9,192,631,770 cycles. Everything above that level is convention, but convention with no ambiguity in it.

Frequently asked questions
How many minutes is 1 hour?
1 hour = 60 minutes. 1 hour = 60 minutes, so the conversion is 1 × 60 = 60. That is exact arithmetic — both units have a fixed definition, so there is no rounding beyond the digits shown.
Is this conversion exact?
Yes. Seconds, minutes, hours, days, and weeks all have fixed definitions — 60 seconds to the minute, 60 minutes to the hour, 24 hours to the day, 7 days to the week. Nothing in this conversion touches a month or a year, so no averaging is involved and the only rounding is in the digits displayed.
