If you need to estimate how many units a product moves on Amazon each month, this converts BSR ranks into sales figures across 12 marketplaces. Three modes: punch in a BSR number with category and price for a quick calculation, drop in an ASIN to auto-fetch the data, or analyze an entire keyword niche to see total market size and how concentrated the competition is. The BSR-to-sales formulas include category multipliers since a rank of 1,500 in Electronics doesn't mean the same volume as 1,500 in Books. No API keys required. Useful for product research, competitor benchmarking, or sizing up whether a niche is worth entering before you commit.
