Welcome to the metric system, the best measurement system ever. Hopefully, this site will help you see why metric is so cool, and how you can learn it and use it.

Congratulations to the Irish for their road sign conversion a few years back! On the 20th of January, 2005, they changed all of their speed limit signs to km/h.

Right now, about 6,000,000,000 people use metric in daily life!

If you are one of the many people who think that the metric system is difficult, or if you just are not familiar with it yet, you can learn what you need to know right here. Choose an item from the menu and see what you've been missing!

It is my intention to give people useful information about the metric system and practical guidance to help them use it in everyday life. This is not the place to find description of technical or scientific units unless a normal, literate person could be expected to know them or encounter them. (For example, there is nothing here about steradians or moles.)
