<P> The average length of a Martian sidereal day is 24 h 37 m 22.663 s ( 88,642.66300 seconds based on SI units ) , and the length of its solar day ( often called a sol ) is 24 h 39 m 35.244147 s ( 88,775.244147 seconds ) . The corresponding values for Earth are 23 h 56 m 4.0916 s and 24h 00 m 00.002 s , respectively . This yields a conversion factor of 1.02749125170 days / sol . Thus Mars ' solar day is only about 2.7 % longer than Earth 's . </P>
