什么是 Units of mass and capacity?

Definition 19.4 Primary & Middle School Mathematics · 第 19 章 — Measuring

Masses are measured in grams (g) and kilograms (kg), capacities (how much a container holds) in liters (L) and centiliters (cL):

1 kg=1 000 g,1 L=100 cL.1 \text{ kg} = 1\,000 \text{ g}, \qquad 1 \text{ L} = 100 \text{ cL}.

示例

Example 19.5

A letter: about 2020 g. A bag of flour: 11 kg. A bathtub: about 150150 L. A glass: about 2020 cL. To balance a scale holding a 11 kg bag against 650650 g of apples, add 1 000−650=3501\,000 - 650 = 350 g on the apples’ side.
