Decimal Time

Progress: 0%

Converting to Decimals

Time is used in calculations for fuel consumption and passage planning.

Time must be converted from hours and minutes to decimal hours to use in a calculation.

For example, one hour and thirty minutes = 1.5 hours

1 hour and 30 minutes
=
1.5 hours

The hours stay the same. Only the minutes change.

3 hours and 30 minutes
=
3.5 hours



2 hours and 15 minutes
=
2.25 hours
