How much steam power makes upvote worth 0.01$

I wonder what is the answer for the title question. I see often good content that I upvote, but my upvote doesnt's has any influence except the fact that there is just one upvote more. It makes me feel that my voice is worth almost nothing. I consider to deposit small amount of money, but I totally don't have idea how much should It be.

Does anybody know the answer for the question how much steam power makes upvote worth 0.01$?
I think the answer will also help others. Thanks in advance for reply.
