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 20 years into months we have to multiply 20 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

20 yr → T_(mo)

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

T_(mo) = 20 yr × 12 mo

T_(mo) = 240 mo

The final result is:

20 yr → 240 mo

We conclude that 20 years is equivalent to 240 months:

20 years = 240 months
