Intro to Unit Conversion

Course:
Chemistry

This is the first of two videos about unit conversion problems. This style of problem solving is also called "dimensional analysis." This video shows you how you can use a conversion factor to change units. Our second video will have examples of using multiple conversion factors. Both videos have example problems. We study unit conversion and dimensional analysis in chemistry class, because it is so useful in solving chemistry problems. But you'll find it helpful in math, physics, engineering...so many different subjects. This video should especially help those new to the metric system and metric conversions - see example 3.

In science classes, you often do problems that require unit conversions. This is especially important for conversions to and from the metric system (pounds to kilograms, for instance).

This style of problem solving is also called “dimensional analysis.” We’ve made two videos that take you through this subject. This first video shows you how you can use a conversion factor to change units. The second video has examples of using multiple conversion factors. Both videos have example problems worked in full.
