What this calculator does
Baseball WHIP works out walks plus hits per inning pitched, the standard measure of baserunners a pitcher allows. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
