I think that's the speed of light.
186000 mi/sec*5280 ft/mi*12 in/ft*60 sec/min*60 min/hr*24 hr/day*365 d/yr
= 3.7165E17 inch/year

We will take the miles to feet to inches,

.



and we will take the seconds to minutes to hours to days to years

Cancelling units which are in a numerator and a denominator:

Change everything to scientific notation:



Group the numbers for multiplication and the exponents of 10
for addition:




Now your calculator can make the multiplication of those numbers:



Next we change  to scientific notation 

and we have:



And we add those powers of 10



With scientific notation your calculator can handle
all numbers regardless of how large.
