If you mean "how many hours are IN one day", then there are 24 hours in a day.
There are 24 hours in a day.
24 hours are in one day...:)
There are 12 hours in a day after noon.
24 hours a day
There are 14.87 Earth hours in 14 Martian days. This conversion is based on the fact that a Martian day, or sol, is approximately 24.6 Earth hours long.
A Martian day, or sol, is about 24.6 hours long, whereas an Earth day is 24 hours long. A Martian year is roughly 687 Earth days, which is longer than an Earth year of 365 days.
One martian day, or sol, is approximately 24.6 hours. So, 90 martian days would be roughly equivalent to about 2,214 Earth hours, or about 92 Earth days.
Mars's day-length is close to that of Earth: 24.7 hours. As such, there are 1.03 Martian days per every one Earth day; or, alternatively, 0.97 Earth days per every one Martian day.
24 hours, 39 minutes, and 35.244 seconds
It would be roughly 345 Earth hours.
Approx. 24.63 hours. so it very similar to Earth's.
The period of rotation is the Martian day, with a length of 24.62 Earth hours (24 hours, 37 minutes, or 1.026 Earth days). The "solar day" is slightly longer, as on Earth, and is about 24 hours, 39 minutes. The Martian "year" (revolution around the Sun) is about 687 Earth days (1.88 Earth years). A Martian day (which the Mars Rover scientists call "sols") is about 24 hours 40 minutes.
The duration of Martian Child is 1.83 hours.
A Martian "sol" (or solar day) is a bit under 24 hours, 40 minutes.
The Martian day is only slightly longer than one on Earth, at 24 hours and 39 minutes.
The average length of a Martian sidereal day is 24h 37m 22.663s (based on SI units), 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 1.027491 sols/day. Thus Mars's solar day is only about 2.7% longer than Earth's.
