Question

How do I convert 1 times 10 to the 20th power seconds to years. Dimensional analysis? 1x10^20 seconds to years

Answer 1

To convert a second measurement to a year measurement, divide the time by the conversion ratio.

Since one year is equal to 31,556,952 seconds, you can use this simple formula to convert:

years = seconds ÷ 31,556,952

1 ×10^20 sec to years = 3.16887646 × 10^12 years
