Formula: Second = Month × 2.63e+06
Multiply any month value by 2.63e+06 to get second.
Reverse: Month = Second × 3.8026e-7

The month originated with the lunar cycle (~29.5 days), used by ancient Mesopotamian, Egyptian, and Chinese calendars. The Gregorian calendar months (28–31 days) are a solar compromise that drifts from the lunar cycle.
Months define billing cycles, salary periods, pregnancy tracking, and seasonal planning. The average Gregorian month is 30.437 days; this conversion uses 30.44 days (2,629,800 seconds) as the standard average.
Interesting fact: The word 'month' derives from 'moon' in Germanic languages. Islam and the Hebrew calendar still use lunar months, which is why Ramadan and Passover shift relative to the Gregorian calendar each year.
The second is the SI base unit of time, defined since 1967 as exactly 9,192,631,770 cycles of radiation from a caesium-133 atom. Before atomic clocks, the second was defined as 1/86,400 of a mean solar day.
The second is universal in physics, chemistry, and engineering. Speed is measured in meters per second; frequency in cycles per second (Hz); radioactive decay in half-lives counted in seconds.
Interesting fact: Atomic clocks are so precise that they would neither gain nor lose one second over 300 million years. The International Earth Rotation Service occasionally adds 'leap seconds' to keep atomic time aligned with Earth's rotation.
Converting month to second is a common task across science, engineering, and everyday planning. The time scale spans from nanoseconds in computing to centuries in history, and having accurate conversions helps when comparing measurements across different systems or disciplines.
As a quick reference: 5 mo = 1.315e+07 s and 10 mo = 2.63e+07 s. For the reverse: 1 s = 3.8026e-7 mo. The exact conversion factor is 1 mo = 2.63e+06 s.
All conversions are performed in IEEE 754 double-precision arithmetic, accurate to at least 8 significant figures.
