Hours to Minutes formula
The factor from hours to minutes is 60.
min = hr × 60
Put another way, one hour is exactly 60 minutes.
Why this factor: the hour and the minute are both defined against the second, so dividing one definition by the other gives 60 directly. Both definitions are set out in full below.
To go the other way, divide by 60 — or use the Minutes to Hours converter, which is the same calculation reversed.

Given 90 hr, multiplying by 60 yields 5400 min.
