Weight and Mass Worksheets – Metric and Customary Units
Weight and mass worksheets help students learn how to measure, compare, and convert different units of weight. These printable worksheets cover metric units such as milligrams, grams, and kilograms, as well as customary units such as ounces and pounds. Students can practice choosing appropriate units, converting between measurements, and solving real-world weight problems.
First, students learn how to identify the correct unit for an object’s weight. For example, a feather weighs in grams, while a suitcase is measured in kilograms or pounds. Then, they practice simple conversions. For instance, 1 kilogram equals about 2.2 pounds. These activities help students build confidence and speed. As a result, they become more comfortable with real-world measurements.
