Abstract: The International System of Units (the SI), the modern metric system, has recently undergone its most revolutionary change since its origins during the French Revolution. The nature of this revolution is that all of the base units of the SI are now defined by fixing values of natural constants. This talk will recall some of the intriguing history of how units have been defined in the past, how it is now possible to define them by fixing constants of nature, and why it was necessary to do so.
