How many years in 500 billion days?

Answer 1

Okay so this is a little tricky to calculate because we have leap years every 4 years, but we know that 4 years have (365*4)+1 days

So, 500,000,000,000 or 5*10^11 years have

5*10^11/4*(365*4+1) days

Which equals:

5*10^11/4*1461 days

Which equals

1.25*10^11*1461 days

Which equals

1826.25*10^11 days

Which finally equals:

1.82625*10^14

Or roughly 183 trillion days

Answer 2

At the present rate of rotation and revolution ...

5 x 1011 days = 1,368,962,874 years.
