When you add salt to bread, and the recipe calls for one teaspoon, a teaspoon of kosher salt is not the same as table salt or sea salt. So how much is it? (It's significantly different.)

When something calls for three cups of flour, and it's a humid day, or a dry day, does that affect the quantity? Yes it does. Significantly enough to affect bread.

Both of the above reasons are why bread bakers weigh all their ingredients, including water.
