This challenge is very similar to that from Day One except the grid is 5x5 instead of 4x4. Once you solve it, you will be asked a unit conversion question. I was asked "How many stones are in 2,794,129 carats?" The answer is 88. For your question, I would suggest doing a Google search for "unit1 to unit2 conversion", without the quotes and where unit1 is the first in your question (in my case, stone) and unit2 is the second (in my case, carat). Just use a calculator to find the answer after that. Since there are 31,751.4659 carats in a stone, I simply divided 2,794,129 carats by 31,751.4659 carats/stone.
Shameless promotion: Since you've made a stop at the Libloggery, why don't you stick around for awhile, read some of the posts, leave some comments, and come back soon!
