使用流程

Use this guide when a converted number affects home recipes, batch cooking, nutrition labels, bakery ratios, and international cookbooks. A reliable result keeps the original value, source unit, target unit, conversion factor, and rounding choice visible.

The goal is not to memorize every factor. The goal is to make the calculation traceable enough that someone else can review it later.

檢查清單

Prefer weight for ingredients that pack differently by volume.
Scale servings before rounding ingredient amounts.
Keep liquid and dry units separate when the recipe depends on texture.

實用事實

Volume-to-weight conversion depends on ingredient density, so flour and water do not share one universal factor.

實用範例

Scaling 4 servings to 10 servings uses a 2.5x factor.

1 tablespoon is 3 teaspoons in US measures.

500 g is about 1.10231 lb.
