In 1.5 minutes: 90 seconds In 1.5 hours: 5,400 seconds In 1.5 days: 129,600 seconds In 1.5 years: 47,335,389 seconds.
About 90 000 seconds or 90 000 000 000 000 nanoseconds.
About 2,840,184,000 seconds in 90 years.
2840140800 seconds
90 seconds = 60 seconds + 30 seconds = 1.5 minutes
90 days = 2 160 hours = 129 600 minutes = 7 776 000 seconds
Considering an average of 365 days per year (not counting leap years) the number of seconds in 90 years would be 90 x 365 x 24 x 60 x 60 = 2838240000
90 seconds
there is 604,800 seconds in 7 days.
