To convert 15 years into months we have to multiply 15 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

15 yr → T_(mo)

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

T_(mo) = 15 yr × 12 mo

T_(mo) = 180 mo

The final result is:

15 yr → 180 mo

We conclude that 15 years is equivalent to 180 months:

15 years = 180 months
