Why weigh such small amounts?

Because baking soda is potent. A teaspoon can weigh between 4g and 7g depending on how packed it is. That 3g difference is enough to ruin the taste of a batch of cookies.

Baking Soda

Baking soda is 3-4 times stronger than baking powder. A measurement error here is fatal: too little means no rise; too much results in a terrible, soapy metallic taste. Being a fine powder prone to clumping, gram-level precision is your safety net.
