Counting to one trillion would take close to 542,241 years.
University of Houston professor Jim Granato stated that it would only take 31,688 years, but that would require you to spit out a number every second!!
You can certainly count to 10 in 10 seconds, but when we start to move onto really long polysyllabic numbers (like 52,375,127,348 for instance) it becomes much more difficult to keep up with 1 number per second.
Therefore, calculating how long it would take to count to a trillion (that's a million times a million) would require a more dynamic formula that takes into account the increased amount of time it takes to name the numbers as the numbers get higher. Our sources came up with a pretty good estimate of 542,241 years.
Either way, don't expect to count to a trillion in your lifetime.
