About Converting Months to Hours
Months and Hours are both everyday units of duration, and converting between them is one of the most routine calculations there is — scheduling, project planning, and billing all depend on it. Months is typically associated with universal (Gregorian calendar), while Hours is typically associated with universal.
Formula
hours = months × 730.485
This factor comes from each unit's defined relationship to the category's base unit: 1 months equals 2629746 base units, and 1 hours equals 3600 base units, so dividing one by the other gives the direct months-to-hours factor of 730.485.
Simple example
1 mo × 730.485 = 730.485 h
1 months = 730.485 hours.
Real-world example
24 mo × 730.485 = 17,531.64 h
24 months = 17,531.64 hours.

History of the Months
The month originated from the Moon's roughly 29.5-day orbital cycle (a 'lunation'), used by many ancient calendars. The Gregorian calendar (1582), used internationally today, decoupled month lengths from the actual lunar cycle to fit 12 months evenly into the solar year, producing the familiar unequal 28-31 day months.
Historical origin. Months was not the invention of a single named person; it developed through the process described above.
Understanding the Hours
Hours (h) measures time. An hour is 60 minutes (3,600 seconds); dividing the day into 24 hours dates to ancient Egyptian timekeeping. It is classified as a Non-SI unit accepted for use with SI.

History of the Hours
The 24-hour day traces to ancient Egypt, which divided daytime and nighttime into 12 parts each using sundials and star-based timekeeping; the modern fixed-length hour (rather than daylight-proportional 'temporal hours') became standard with the spread of mechanical clocks in medieval Europe.
