If I was born on mercury and I am 10 years old on earth, how old would I be?

88 * 58.646=5,160.848

mercury year = 5,160.848 hours

earth year = 8,760 hours

10 years = 87,600 earth hours

10 years = 51,608.48 mercury hours

51,608.48/88

you would be 51,608.48 mercury hours old

you would be 880 mercury days old

still 10 mercury years old?

I believe you will be 41.5 yrs old and 62.3 days old

Your next birthday will be about in may
