- 1). Multiply your hour by 60. In the time 05:30:25, which is 5:30 a.m., you would get 300. For 14:45:50 hours, which is 02:45 p.m., multiply 14 by 60 to get 240. This is the hour-to-minute conversion.
- 2). Add the minutes in your time to the hour-to-minute calculation from the previous step. In 05:30:25, add 300 to 30 to get 330 minutes. In 14:45:50 hours, add 45 to 240 to get 285 minutes.
- 3). Add the seconds together, which may increase your time in minutes by one. Add 25 to 50 to get 75. If the number is 60 or higher, add 1. Otherwise, round down. This is necessary if adding two times together.
