The Metric System: Units and Conversion

1. The Metric System: Units and Conversion

Just like you and your friend communicate using the same language, scientists all over the world need to use the same language when reporting the measurements they make. This language is called the metric system. In this lesson we will cover the metric units for length, mass, volume, density and temperature, and also discuss how to convert among them.

U.S. Customary Units to Measure Weight

2. U.S. Customary Units to Measure Weight

Watch this video lesson to learn how the U.S. measures weight and how you can convert between them. Learn the conversion numbers that you need for each conversion along with the proper operation.

U.S. Customary Units to Measure Capacity

3. U.S. Customary Units to Measure Capacity

After watching this video lesson, you will know how capacity or volume is measured in the U.S. You will know the units that are used as well as how to convert between the units.

Measuring Temperature & Converting Units of Temperature

4. Measuring Temperature & Converting Units of Temperature

In this video lesson, we will learn what temperature is, how we measure it and the units it is measured in. We will also learn how to convert easily between the different units using simple conversion factors.

Speed, Velocity & Acceleration

5. Speed, Velocity & Acceleration

Speed and velocity are not the same thing. Objects' speed and velocity can be identical or very different, depending on their directions of motion. In this article, learn more about these foundational physics concepts, including acceleration and free-falling objects.

How to Convert Standard Units of Measure

6. How to Convert Standard Units of Measure

The United States uses pounds, miles and Fahrenheit for measurements, but the rest of the world uses the metric system. This video lesson will help you to convert from one to the other easily, so you can understand kilometers and kilograms, too.

Unit Conversion and Dimensional Analysis

7. Unit Conversion and Dimensional Analysis

How is solving a chemistry problem like playing dominoes? Watch this lesson to find out how you can use your domino skills to solve almost any chemistry problem.

Scientific Measurements: Accuracy, Precision & Percentage Error

8. Scientific Measurements: Accuracy, Precision & Percentage Error

Accuracy, precision, and percentage error all characterize scientific measurements and tell you something about how good the measurements are. In this lesson, learn what these terms mean and how to calculate percentage error.

Significant Figures and Scientific Notation

9. Significant Figures and Scientific Notation

Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.

Using Measurement to Solve Real-World Problems

10. Using Measurement to Solve Real-World Problems

This lesson uses fundamental and derived units with unit conversions to solve real-world problems like interpreting blueprints, counting the calories of a low-fat food, and estimating arrival time for high-speed driving.
