Ok, I was just doing random math problems and I thought 'how many hours are in a day on Mars?' I can't find the answer. I was just wondering...

Almost the same as Earth. 24h37m
EDIT: This is the sidereal day. There is a difference between that and a solar day (which is the 24 hour one on Earth) It is small, however.
EDIT2: Encyclopedia Britannica online:
rotation period (Martian sidereal day) 24 h 37 min 22.663 s
Martian mean solar day (sol) 24 h 39 min 36 s

3 seconds on wikipedia tells me that Mars rotates in 24.62296 Earth hours. nineplanets.org has the same value.
A Mars day is called a "sol".
A Mars day is called a "sol".

The average length of a Martian sidereal day is 24h 37m 22.663s in terms of Earth hours, and the length of its solar day is 24h 39m 35.244s (the latter is known as a sol, more precisely 88,775.24409 seconds). The corresponding values for Earth are 23h 56m 04.2s and 24h 00m 00.002s, respectively. This yields a conversion factor of 1.027346 sols/day. Thus Mars's solar day is only about 2.7% longer than Earth's.
