How to Convert Time to Decimal

For the default time of 2:45:45 in the converter, let's convert to just hours, then just minutes, and then just seconds. We will need to convert each part into the unit of time we want.

2:45:45 is 2 hours, 45 minutes, 45 seconds. And we know that 1 hour = 60 minutes and 1 minute = 60 seconds so 60 minutes/ hour * 60 seconds/ minute = 3600 seconds/ hour or 1 hour = 3600 seconds.

To convert time to just hours:

• 2 hours is 2 hours * (1 hour/ 1 hour) = 2 hours
• 45 minutes is 45 minutes * (1 hour / 60 minutes) = 45/60 hours = 0.75 hours
• 45 seconds is 45 seconds * (1 hour / 3600 seconds) = 45/3600 hours = 0.0125 hours
• Adding them all together we have 2 hours + 0.75 hours + 0.0125 hours = 2.7625 hours

To convert time to just minutes:

• 2 hours is 2 hours * (60 minutes / 1 hour) = 2 * 60 minutes = 120 minutes
• 45 minutes is 45 minutes * (1 minute / 1 minute) = 45 * 1 minutes = 45 minutes
• 45 seconds is 45 seconds * (1 minute / 60 seconds) = 45/60 minutes = 0.75 minutes
• Adding them all together we have 120 minutes + 45 minutes + 0.75 minutes = 165.75 minutes

To convert time to just seconds:

• 2 hours is 2 hours * (3600 seconds / 1 hour) = 2 * 3600 seconds = 7200 seconds
• 45 minutes is 45 minutes * (60 seconds / 1 minute) = 45 * 60 seconds = 2700 seconds
• 45 seconds is 45 seconds * (1 second / 1 second) = 45 * 1 seconds = 45 seconds
• Adding them all together we have 7200 seconds + 2700 seconds + 45 seconds = 9945 seconds
