31556926 seconds in a year
1 second = 1000 milliseconds 1 year = 31556926 seconds ⇒ 2 years = 2 x 31556926 x 1000 milliseconds = 63113852000 milliseconds

31556926 seconds in a year
1 second = 1000 milliseconds 1 year = 31556926 seconds ⇒ 2 years = 2 x 31556926 x 1000 milliseconds = 63113852000 milliseconds
1 year = 31556926 seconds (≈ 31.6 million seconds) ⇒ 1 million seconds = 1000000 seconds = 1000000 ÷ 31556926 years ≈ 0.0317 years
One year is slightly less than 365.25 days, coming in at 31,566,926 seconds. Thus: 1 second = 1/31556926 year ~= 3.169 x 10-8 year
31556926 in a year x 14 years =441796964 seconds

10 to the 8th doesnt mean square. 108 means to the power of eight. it means 10 times 10 times 10 times 10 times 10 times 10 times 10 times 10. in other words its 10 times 10 eight times. 5.7*108 = 570,000,000 = 570 million
