Practice Weight Measurement in Math
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
Measuring how heavy something is using standard units such as grams, kilograms, ounces, and pounds, by comparing an object's weight against known reference amounts on a balance or scale.
A balance scale is like a seesaw—the heavier side goes down. To find out how heavy something is, add known weights to the other side until the scale balances perfectly.
