Summary
Converting metric units is as easy as sipping chocolate milk…unless you’re King Henry, that is! In this BrainPOP movie, Tim and Moby demonstrate how easy it is to convert centimeters to dekameters or kilograms to milligrams. Whether you’re dealing with length, mass, or volume, you’ll learn that each quantity is measured with one base unit. You’ll see how a range of new units can be created by adding prefixes to these units, and discover why the decimal point is key to converting between them. And you’ll find out exactly what King Henry, chocolate milk, and a nifty mnemonic have to do with it all!
