Conversion formula
How to convert 424 days to months?

We know (by definition) that: $1 d \approx 0.032854911 mo$

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

\frac{1 d}{424 d} \approx \frac{0.032854911 mo}{x mo}

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

x mo \approx \frac{424 d}{1 d} * 0.032854911 mo \to x mo \approx 13.930482264 mo

Conclusion: $424 d \approx 13.930482264 mo$

424 days is equivalent to 13.9304823401602 months

Units involved

This is how the units in this conversion are defined:

Days

"A day is a unit of time. In common usage, it is either an interval equal to 24 hours or daytime, the consecutive period of time during which the Sun is above the horizon. The period of time during which the Earth completes one rotation with respect to the Sun is called a solar day. Several definitions of this universal human concept are used according to context, need and convenience. In 1960, the second was redefined in terms of the orbital motion of the Earth, and was designated the SI base unit of time. The unit of measurement day, redefined in 1960 as 86 400 SI seconds and symbolized d, is not an SI unit, but is accepted for use with SI. A civil day is usually 86 400 seconds, plus or minus a possible leap second in Coordinated Universal Time (UTC), and occasionally plus or minus an hour in those locations that change from or to daylight saving time."

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."
