1 s = 0.00027777777777778 hr

To convert 900 seconds into hours we have to multiply 900 by the conversion factor in order to get the time amount from seconds to hours. We can also form a simple proportion to calculate the result:

1 s → 0.00027777777777778 hr

900 s → T_(hr)

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

T_(hr) = 900 s × 0.00027777777777778 hr

T_(hr) = 0.25 hr

The final result is:

900 s → 0.25 hr

We conclude that 900 seconds is equivalent to 0.25 hours:
