How to Convert Seconds to Hours
Example: How many hours are equivalent to 70.29 seconds?
As;
1 seconds = 0.000277777 hours
70.29 seconds = Y hours
Assuming Y is the answer, and by criss-cross principle;
Y equals 70.29 times 0.000277777 over 1
(i.e.) Y = 70.29 * 0.000277777 / 1 = 0.01952494533 hours
Answer is: 0.01952494533 hours are equivalent to 70.29 seconds.
