Chapter 2 Review: Units of Measure

Chapter 2 Review: Units of Measure Hint! You should be able to calculate an object’s density with liquid displacement (given the before and after volume) and reading a balance (before and after mass).

Chapter 2 Review: Calculations Conversion Factor- a ratio derived from the equality between two different units that can be used to convert from one unit to another. Dimensional Analysis- a mathematical technique that allows you to use units to solve problems involving measurements.
