How many months in 100 years?

Conversion formula

The conversion factor from years to months is 12, which means that 1 year is equal to 12 months:

1 yr = 12 mo

To convert 100 years into months we have to multiply 100 by the conversion factor in order to get the time amount from years to months. We can also form a simple proportion to calculate the result:

1 yr → 12 mo

100 yr → T_(mo)

Solve the above proportion to obtain the time T in months:

T_(mo) = 100 yr × 12 mo

T_(mo) = 1200 mo

The final result is:

100 yr → 1200 mo

We conclude that 100 years is equivalent to 1200 months:

100 years = 1200 months

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 month is equal to 0.00083333333333333 × 100 years.

Another way is saying that 100 years is equal to 1 ÷ 0.00083333333333333 months.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that one hundred years is approximately one thousand two hundred months:

100 yr ≅ 1200 mo

An alternative is also that one month is approximately zero point zero zero one times one hundred years.

Conversion units

The units involved in this conversion are years and months. This is how they are defined:

Year

A year (symbol: y; also abbreviated yr.) is the orbital period of the Earth moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by changes in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the globe, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period as counted in a given calendar. The Gregorian, or modern, calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days.

Month

A month (symbol: mo) is a unit of time, used with calendars, which is approximately as long as a natural period related to the motion of the Moon; month and Moon are cognates. The traditional concept arose with the cycle of moon phases; such months (lunations) are synodic months and last approximately 29.53 days. From excavated tally sticks, researchers have deduced that people counted days in relation to the Moon's phases as early as the Paleolithic age. Synodic months, based on the Moon's orbital period with respect to the Earth-Sun line, are still the basis of many calendars today, and are used to divide the year.
