The orbital period of Mercury is 1.9 years. To convert this to seconds, we need to multiply by the number of seconds in a year. There are 365.25 days in a year, and 24 hours in a day, and 60 minutes in an hour, and 60 seconds in a minute. So, there are 365.25 * 24 * 60 * 60 = 31,557,600 seconds in a year. Multiplying this by 1.9 gives us 59,709,600 seconds, which is closest to 6 billion seconds.
