The conversion factor from seconds to years is 3.1688738506811E-8, which means that 1 second is equal to 3.1688738506811E-8 years:

1 s = 3.1688738506811E-8 yr

To convert 401.6 seconds into years we have to multiply 401.6 by the conversion factor in order to get the time amount from seconds to years. We can also form a simple proportion to calculate the result:

1 s → 3.1688738506811E-8 yr

401.6 s → T_(yr)

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

T_(yr) = 401.6 s × 3.1688738506811E-8 yr

T_(yr) = 1.2726197384335E-5 yr

The final result is:

401.6 s → 1.2726197384335E-5 yr

We conclude that 401.6 seconds is equivalent to 1.2726197384335E-5 years:
