An online calculator to convert time from decimal to hours, minutes and seconds using the facts that
1 hour = 60 minutes
1 minute = 60 seconds.
Convert 2.13 hours to hours, minutes and seconds.
The whole part 2 is the number of hours
The decimal part 0.13 is less than one hour and is therefore converted to minutes as follows
0.13 hours = 0.13 × 60 minutes = 7.8 minutes
The whole part 7 in 7.8 is the number of minutes
The decimal part 0.8 minutes is now converted in seconds as follows
0.8 minutes = 0.8 × 60 seconds = 48 seconds.
2.13 hours = 2 hours , 7 minutes and 48 seconds.
