This yields a conversion factor of 1.02749125170 days/sol. Thus Mars' solar day is only about 2.7% longer than Earth's. A convention used by spacecraft lander projects to date has been to keep track of local solar time using a 24-hour Mars clock on which the hours, minutes and seconds are 2.7% longer than their standard (Earth) durations.
