By hivestats your 100% vote should be 0.14$ but your VP is low. Let it refresh.
It could also be that you are voting on posts/comments that have less than 50k or 100k HP (don't remember the exact amount it takes) in votes which reduces the power of your vote.
RE: Can anyone help me find why 4K in Hive Upvotes are $0 but 1000 steempower is $0.05 ?
