1 billion = 1x10^9
Use dimensional analysis (or the "dot-bar method"):
1x10^9 s | 1 h / 3600 s | 1 day / 24 h | 1 yr / 365 day | = 31.7 yr
That's about 31 years and 8 months and 2 weeks, give or take a couple days.
Also, it would be near impossible to pinpoint the EXACT time this happens with our conventional timekeeping methods. Not only do leap years add an extra kink into the equation, but leap SECONDS, as well. Still, 31.7 years is aout right.

one billion seconds = about 31 years 8 months and 12 days
roughly of course.

thats easy take 1 billion and devide by 60 to get minutes then devide that answer by 60 to get hours then by 24 to get days and by 365 to get the nearest answer in years.
About 31 years, 8 months, 15 days, 12 hrs, 36 min, and 10 seconds. Check my math.
