How to Convert Days to Seconds
Example: How many seconds are equivalent to 45.55 days?
As;
1 days = 86400 seconds
45.55 days = Y seconds
Assuming Y is the answer, and by criss-cross principle;
Y equals 45.55 times 86400 over 1
(i.e.) Y = 45.55 * 86400 / 1 = 3935520 seconds
Answer is: 3935520 seconds are equivalent to 45.55 days.
