1 billion = 10 to power 12 (according to SI units)
12 billion = 12 x 10 to power 12
1 year = 86400 x 365 = 31536000 seconds
12 billion = 12 to power 12 x 31536000 = 3.78432 E20 or 378.432 trillion

12 years = 144 months = about 626 weeks = about 4383 days on average = about 105,190 hours on average = about 6,311,390 minutes on average = 378,683,424 seconds on average (not counting leap seconds)
1.0X 10^12 seconds (1 hour/3600 seconds)(1 day/24 hours)(1 year/365 days) = 31,709.8 years
well 1 billion seconds is equal to just over 31 years 251 days and 12 hours. You do the math but its around 2.5 billion secs.
12 years is 378,683,112 seconds.

12 seconds^^
12 billion years
12 years = 378,683,112 seconds.
1 billion years is equivalent to 12 billion months. This is because there are 12 months in a year.
3 hours = 3 hours PAST 12 o'clock = (3 x 1 billion) - 4.6 billion = 3 billion - 4.6 billion = -1.6 billion years = 1.6 billion years ago6 hours = 6 hours PAST 12 o'clock = -1.6 billion years + (3 x 1 billion) = -1.6 billion + 3 billion = 1.4 billion years ago

The International Astronomical Union definition of a second gives 31,557,600 seconds in a year. That makes 12 years = 378,691,200 seconds. And that is not counting the leap-second corrections that are made from time to time.
Earth is about 4.5 to 4.6 billion years old. The universe is about 13.7 billion years old.
60 x 60 = 3600 in 1 hour 3600 x 24 = 86400 in a day 8600 x 365 = 31,536,000 in a year 31536000 x 12 = 378,432,000 in 12 years
