Result

The conversion result is: 4 years is equivalent to 48 months.^[1]

Conversion formula
How to convert 4 years to months?

We know (by definition) that: 1 yr = 12 mo.

We can set up a proportion to solve for the number of months.

1 yr / 4 yr = 12 mo / x mo

Now, we cross multiply to solve for our unknown x:

x mo = (4 yr / 1 yr) * 12 mo → x mo = 48 mo

Conclusion:

4 yr = 48 mo

Conversion in the opposite direction

The inverse of the conversion factor is that 1 month is equal to 0.0208333333333333 times 4 years.

It can also be expressed as: 4 years is equal to 1 / 0.0208333333333333 months.

Approximation

An approximate numerical result would be: four years is about zero months, or alternatively, a month is about zero point zero two times four years.

Units involved

This is how the units in this conversion are defined:

Years

"A year is the orbital in which Earth moves 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."

Months

"A month 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 Moons 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."
