Once you get used to the Metric system, you'll realize that it is massively superior to either Imperial or US measurement. I am Canadian and we have been metric for some 45 years now. There are those who refuse to use the superior system, but they are slowly disappearing. The trick is to simply use it. Don't try to convert one system to another. Just use it. You will quickly get used to it.
A perfect example is temperature. In the metric system, zero is the freezing point of water, 100 is the boiling point of water, 20 is comfortable room temperature or a nice spring day. Thirty is damned hot and -30 is damned cold. All else falls in between. What else do you need to know?
By the way, kilo and metre is kil'ometre. Kilom'eder is not a word and it is a massively common error. Wake up!
-Perhaps some sort of a fraction (plus or minus) was used to divide a chain into smaller parts in those days?
